Does that replace the entire procedure?

My diskkabel is apparently messed up as I get immediate reboots…

/* step 5 load remaining 15 sectors off disk */
dodisk:
mov $0x1f6,%edx
inb %dx,%al
andb $~0x40,%al #clear LBA bit
NOP
outb %al,%dx

可以在QEMU 2.8.1（debian 1:2.8+dfsg-6 + deb9ut）运行

Disclaimer: I’ve never done it, either. Your best bet would be to start with http://gunkies.org/wiki/Installing_386BSD_on_BOCHS and then compile 2.0 using that setup.

The 386BSD 2.0 source (https://github.com/386bsd/386bsd) does have an installation program (/install), but it seems that it expects a very specifically formatted filesystem. There is no documentation on how to set up a system that can make use of the installer, much less from scratch on a non-386BSD system.

I spent about an hour and got 386BSD disklabel to do something useful-ish on a modern GNU/Linux and wrote bootstrap code to a floppy. Then I decided I didn’t care anymore when I realized that (a) probably QEMU’s shoddy floppy emulation would give me trouble again, and (b) even if I got newfs to work as well, I’d still have no way to actually fill the filesystem with the data required to get anywhere.

I never installed it.
