Hoping someone can help me here...
I have a Zenith 386sx/20 Laptop w/ a 387 Co-Processor, 4 megs of memory, and
a 60 Meg HD. At one point I did have FreeBSD v2.0.5 running on it, but
removed it because I needed a temporary DOS platform. Now when I'm
re-install FreeBSD with the v2.0.5 boot disk, I go through the following
process:
[standard boot...]
640K Base Memory, 03072K Extended
384K Shadow RAM, 00000K Expanded
>> FreeBSD BOOT @ 0x10000: 639/3072 k of memory
[... Usage, blah blah, etc...]
Boot:
Booting fd(0,a)/kernel @ 0x20c000
text=0xfc000 data=0x0 bss=0xa00 symbols=[+0x600+0x4+0x27c+0x4+0x1fb]
total=0x30947f entry point=0x20c00
Uncompressing kernel...
[... probing all the devices, no probs, blah blah...]
rootfs is 1000Kbyte complied in MFS
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0

code segment = base 0x0, limit 0xfffff, type 0x1b

current process = 1 (swapper)
interrupt mask = net tty bio
panic: page fault
syncing disks... done
Automatic reboot in 15 seconds - press a key on the console to abort

And that's it. I'm using the FreeBSD v2.0.5 boot.flp that's currently
available on the ftp sites. I remeber though at one point there was an
alternate boot.flp for 2.0.5 for "low memory" systems (e.g. 4 megs), but
that's no where to be found on the sites I've looked at. Is that what I
may have used & need? If so, where can I get a hold of it?
Or is it something more (e.g. My physical memory has been corrupted some how...)
(I have also tried the 2.1 boot.flp (even though 2.1 requires 5 megs), and I
get the exact same result as above...)

Any help would be greatly appreciated,
Thanks,
Matt Peterson
