I’d never heard or seen this before, and yeah it’s some MIPS’isim.
Apparently it’s something called a “global offset table” which of course has a 64k entery limit which can cause an overflow if you are doing something crazy like running a disassembler and having tens of thousands of instructions.
Looking at the GCC MIPS options page, there is hope, one can opt for a more iniffecient and larger table with the simple option of -mxgot
While discussing various non x86 boards the topic came up about the Chinese government MIPS based processors, namely the Loongson-3A4000. I’ve tried several times on the past to buy one with no success however 2020 would make up with it as 2 separate leads yielded boards.
To me, there is a great deal of confusion around this setup as it goes by different names, and is sometimes spelt in English, other times Chinese (Simplified & Traditional) with different part numbers and vendors making it kind of confusing.
Various names include, but not limited to:
ICT Loongson-3A R4(loongson-3A4000)
I don’t want to sound like I’m going to just shit all over this thing, but it’s not free, it’s not subsided, and it’s not cheap. Weighing in at 元3,500 RMB the LX-6901 is not a machine for the masses, however it is a non x86 machine for the classes.
Thanks to my day job I was able to get my buyer to trace down several companies, and ads placed on TaoBao and another from AliExpress. Last time I tried both routes, along with the board manufacter Lemote, I was unable to get anything. This time however both leads would work out so now I have 2.
I was told that it would take upwards of 2 weeks for the order(s) to be fulfilled and I should have them in 3 weeks. However 4 business days later this box arrived in my office:
I suspect they need to temper people’s expectations on shipping, but luckily for me I’m not over seas, although shipping from China to Hong Kong does require a special permit for electronics.
Clearly the tape had been opened several times for various inspections as this shipment was destined to be exported. But props on the dragon tape!
As expected, two boards! Oddly and confusing enough both suppliers insist the boards are different.
Natrually, they are of course identical.
Here is a better glimpse at the board.
The Lemote LX-6901 is not without faults however, it has a memory controller issue and cannot operate correctly with 2 sticks of ram. Luckily my DDR4 extras are 16gb so it’s not bad for messing around. The board also can post ATI boards. However it doesn’t like my Asus Radeon R9 380 Strix board, although it posted fine. I have a few of the FirePro W2100 cards, not a remarkable card, but it does work.
In addition you do need a specific OS for the board, on vendor on AliExpress was unwilling to send me anything, while another on TaoBao was willing to send me UnionTech’s UOS.
the M.2 slot works fine and I was able to boot from USB, and install UOS. The BIOS is very ‘PC’ like, pressing ENTER will enter the bios, and you can change boot priorities, or drop to the UEFI shell if you so please.
Installation is pretty easy and straight forward. There is only a few options during install, the desination, if you should accept the default layout (why not)? and a language
The USB stick is slow, but it didn’t matter as I only needed to install twice. The first time I had both memory slots populated, and the board crashed at 5% of the install. I was able to do some searching around and found out about the bad memory controller, so popping out one of the DIMMs and I was able to install and use the machine.
UOS for the MIPS however is a seeming commercial product that is very difficult to buy outside of China (it may very well be allocated only for certain circles as you need a Chinese cellphone number, government ID, and some kind of project id?), although I’m still trying.
The phone support was useless, and I’ve had a few email exchanges on asking if it’s available for purchase, and if so how much. I’ll update if I can figure it out.
What does suck is that while UOS is not authorized you can’t get any OS updates, nor can you enable to root user. So yeah you can’t effectively own the machine with UOS. There is a ‘trial’ mode to enable a 90 day ‘grace’ period so at least I can add GCC and at least build software. Clearly if I can’t sort out UOS I’ll have to dump the kernel / initrd and restore another MIPS64EL Linux distro over the filesystem. Debian has MIPS64EL, and seems to be working to mainline the LX-6901.
UOS bills itself as a Windows replacement, and I have to say that I do enjoy using it. It has some rather ‘Windows’ qualities to it, like the sound mixer, and ease of installing apps from the ‘store’ however if it’s not in the store and it’s Not authorized you are out of luck. As much as I dislike distro of the week nonsense, I do like the idea of thousands of people being hired to flesh it out to make Linux usable, but only time will tell how much of it is translation to Chinese, and how much is developing software.
When it comes to performance the 3A4000 running at 1.8Ghz is faster than a Raspberry Pi 4, however not significantly faster CPU wise. However the big plus the MIPS does have is that it has a far more capable bus with M.2 and PCI-E slots along with SATA giving the board much better IO than any SOC solution like the Pis.
I built the BYTE Benchmark 5.1.3 and did this graph with data from running on a Zero for comparison. I had to adjust scales for some of this so its more visible, however the important data is here that CPU wise they are close together, but in the area of IO the Dragon pulls far ahead. For those who like the Linux boot score, the CPU ‘clocks’ in at 3594.02 BogoMIPS per core.
It’s been a large ‘discovery’ thing, and a long time since I’ve tried to make Linux a ‘daily driver’ and of course the scarcity of MIPS binaries on Linux is going to be an issue, but I’ll have to explore the apparent ARM/x86 compatibility as I can find more information about it.
I don’t know how much (if any) reach my blog has in China, but if anyone knows any more or can help, drop a line!
In the world of “If you can’t encourage an exclusive, buy it” here we are at this crossroad again. With the new MS console getting ready to be pushed out into the world, there is no doubt that we are not only in for a new deluge of Skyrim ports, but the much anticipated Starfield should be appearing on nextgen consoles, the best way to keep it exclusive is to just buy the beleaguered studio, and push onwards.
No doubt the fallout from … Fallout 76 has burnt a lot of people, so this may just further isolate their diminishing fan base, only time will tell. Or normies just don’t care about FO76 as it was some MMMMOOOORPG thing that normal people don’t care about, and all they want to do is kill dragons, and shoot lazzer beams from their hands.
One thing that is kind of fitting is that the culture of ‘release it and patch it in the field’ is in safe hands at Microsoft!
Way back in the late 90’s from the University of Utah there was this fantastic project that promised to bring Operating System construction to mere mortals but taking existing PC operating systems, Linux, NetBSD, FreeBSD and break them down to their best components, and then interlink them using COM allowing you to glue the best parts together like lego.
And the project was called OSKit.
It was fantastic for something unknown at the time for creating so called ‘bare metal programs’ that didn’t have a real operating system, but rather could use operating features like LIBC, or the EXT2 filesystem. It was almost that level of ‘MS-DOS’ like feeling from protected mode, but being able to take more stuff with you.
And of course transforming the ELF into a multiboot executable that GRUB can load:
And now you are ready to boot, on say Qemu?
I was kind of surprised it never really took off, maybe it was too far ahead of it’s time. The most notable project I’ve seen that used it was OSKit-Mach, although they later on abandoned OSKit.. I’m not sure why but I would suspect the lack of updates post 2002 would have something to do with it.
Building this was… Interesting as I recall this being somewhat difficult, and I know I’ve probably made it more difficult, but I thought it would be ‘fun’ using the tools of the time. And 1999 has us at Debian 2.2r0. Which thankfully is on archive.org and is a mere 3 CD-ROMS for the i386 binaries. Installing that into VMWare wasn’t so difficult, and swapping CD images around I was able to get enough installed to start building things. For those of you who don’t want to install Debian, here is my pre-compiled Linux on Linux toolchain: i586-linux2.tar.gz. It’s i386 on i386, so you will need to be able to run i386 ELF exe’s. For OS X users that haven’t installed Catalina, you can try OSX-Linux-2.00-i586-gcc2723.tar.gz
I should point out, that although things have to be patched around for older versions of OSKit, 20020317 does build fine using GCC 2.95.2 (20000220) from Debian 2.2r0. So if you want to build in a VM, then you really don’t need any of this. But I’m strange, and I have my WSL2 Debian 10 to think about. So the easiest way to build GCC 2.x is with GCC 2.x so why not start in Debian?
First let’s prep our destination directory, and populate it like a good little cross compiler:
And now I can build stuff!… I then tar’d if up and copied it to my WSL instance, and now I can cross compile fine (a big plus of WSL2 is that you can install the 32bit support, and run old EXE’s! Take that Apple!)
Now it’s worth noting that a few things need to be edited, the ‘OSKit on UNIX’ thing won’t build cleanly and I didn’t investigate as Qemu is a thing now. So disable it in the modules.x86.pc file. Then run configure like this:
sh configure --host=i586-linux --prefix=/oskit --build=i586-linux --enable-modulefile=modules.x86.pc
Despite using the host, build or target setting it doesn’t pick up prefix of our cross compiler, so you have to manually edit Makeconf
Be sure to change the tool exports to look like this:
And finally remove -fno-strict-aliasing from OSKIT_FFLAGS, and now you can build!
The bonus is that it’ll build well under a minute on a modern machine.
As mentioned above you should now be able to take the hello world example kernel, and transform it to a multiboot, and boot it via grub.
Again this was such an exciting project I’d hate for it to just suddenly die in absolute obscurity. Maybe it’ll inspire others to try “assisted bare metal” programs, there was a DooM OS, among others in the era.
Again super thanks to shadyjesse for finding and fixing the larger issues, and philpem for his great emulator, freebee!
I have to say, having never played with an AT&T Unix PC, it’s kind neat with this windowing non X11 UI. Although even in emulation it’s incredibly slow. But such was the Unix microprocessor revolution of the era, it’s crazy to think the mighty SUN-2 is also on the same level of performance, although SUN would at least go the way of the 68020 before giving up on the 68k for SPARC.
Even though the 68000 lacked the ability to recover from bus faults, allowing a better path to UNIX with the 68010, OEM’s still brought their own MMU technology to flesh it out, leading to divergent systems. Not that it mattered all that much for AT&T as they started to establish themselves as the new defacto go to UNIX vendor they quickly abandoned the market leaving the Unix PC, and 3B2’s to die off. While so many like to think that the ‘Unix’ business is booming, it really only boomed once AT&T exited the market until Linux had started to gain enough mindshare post 1.0… Which also included 68000 support, although aimed for the the stronger 68030/68040’s.
Anyways I’m sure you didn’t come here for my ramblings about the 68000 instead you want an easy to run package to click and GO!
There are two executables, for normies, tourists, and people only wanting to witness the fun it doesn’t matter which one you use. For anyone wanting to install the 3B1 Unix, you’ll want “freebee-10sec-O2.exe”. Since the 3B1 uses a non standard format, if you want to use FAT 360kb disks from a PC emulator then you’ll need “freebee-9sec-O2.exe”. Isn’t compatibility great?
I don’t get how this is a search term, all about “Ну вот” so I guess I’ll poison the well.

32bit computing arrived to the masses. Although it’s incredibly frail by modern standards, Windows 95 did deliver on the promises of OS/2. Depending on your apps, and drivers of course. Although OS/2 did have int13.sys to pass disk calls to a special v86 machine which then used the disk BIOS to make disk access possible, Microsoft and IBM stopped short there, not going all the way letting OS/2 use MS-DOS device drivers. Windows 95, however could.
This was always the winning strategy of Windows, is that it relied on the incredible OEM driver support for MS-DOS. Of course this would also be a catastrophic weakness. From my personal experience being able to leverage ancient MS-DOS drivers also helped squeeze as much as possible out of existing hardware. Case in point, the NDIS2 drivers for the AT&T Starlan 1mbit cards worked fine under Windows 95, additionally you could lost just the lower level drivers, and 95 could then load it’s protocols on top of that stack allowing you to have a TCP/IP network over that 1mbit Starlan stack letting you telnet into your 3b2 (or setup SAMBA, and doing file/print sharing).
If anything the biggest flaw of Windows 95 was not installing TCP/IP by default. However unlike many OS’s of the time, Windows 95 did include LAN and dialup stacks. There was plenty great about OS/2, but it’s refusal to integrate networking into the operating system hamstrung things like named pipes, peer, and larger apps, as you would have to buy and license a stack of stuff to bring OS/2 up to where it should be, while NT and 95 were complete out of the box.
Windows 95 was an excellent bridge OS for the era, until OEMs finally got around to writing drivers for Windows NT. Once the mainstream could finally take that leap, and leave MS-DOS far behind. But that didn’t really happen until Windows XP.
That being said, the favorite thing is to run Windows 95 in a browser. I found https://copy.sh/v86/ the fastest and best, as it loads a short 6MB compressed core image, and you are instantly teleported to the 95 desktop.
I have this old toolchain that relies on MSYS 1.0 from 20+ years ago. It’s great. I know others always love the newer, but I’m happy with this one.
Well this morning I wanted to rebuild some Qemu 0.90 thing and I got this fun error trying to run configure:
0 [main] us 0 init_cheap: VirtualAlloc pointer is null, Win32 error 487
AllocationBase 0x0, BaseAddress 0x71110000, RegionSize 0x440000, State 0x10000
d:\mingw\msys\bin\bash.exe: *** Couldn't reserve space for cygwin's heap, Win32 error 0
What the heck?! MSYS uses cygwin? I guess I should have known. So the solution is to ‘rebase’ the DLL, as it tries to take a static ‘grab’ at some memory block, because…. I guess subsystems or loaded DLL’s suck?
I rebooted and got the same error.
So obviously it’s a lot more involved.
So looking the rebase I have is part of the Platform SDK. Maybe there are others.
D:\MinGW\msys\bin>"D:\MinGW\include\directx\Microsoft Visual Studio 8\VC\PlatformSDK\Bin\rebase" -b 0x50000000 msys-1.0.dll

And now I can run stuff again. YAY.
I’m sure this has been covered time and time again, but you know it’s mostly to remind me in another 20 years.
However, with the latest updates, from github, adding in a prior botched attempt, and some messing around, and finally, I got it to ping at first, then it was a matter of where to place the ‘slirp tick’. I first though putting it on the interface poll was a good spot, but for some reason the machine causes a deadlock/stall on boot before the PROM can even initialize. I’m not sure why. Searching further I found a good timer portion and injected the code. And sure enough I was greeted with the login banner:
I’ve been able to paste in about 100kb of a uuencoded tar file, and it didn’t lock the VM, and I was able to uudecode it, and actually build the source (Infotaskforce ’87 if anyone cares). So I’m at the point I think it’s stable enough to shove into the world, although I guess until I revisit it again.
Seriously, the sad thing is that they wasted all their time, and bandwidth. The good thing is that PHP7 is far better at this, than PHP5. I know it’s not hipster neaveaux but PHP7 is really awesome stuff.
I didn’t wake up to a million messages about being down, rather a look at what was going on showed me this:
Obviously something is up.
I checked Cloudflare:
All those hits, and no change in user traffic. So I’m not popular.
And it’s all from the United States. Going back to WordPress I can see it’s mostly from one user!
A look through the 30MB log, and it’s a broken site scrape
This is just terrible you are quoting the link to the link, having slashes going every which way. What the heck!? Don’t be a jerk, pace the thing, why are you trying to DOS it? While my hosting is clearly not robust, why can’t you wait a few seconds between each query? Also look at the output and URL’s it’s sending it’ll never work!
