i have dos installed on the internal cflash - i boot it by removing the
32M cflash (32M in, boot linux via lilo, 32M out, boot dos on internal sundisk)
I use a slackware 4 setup that I painstakenly paired down a couple years
ago for this...
booting with lilo was a pain, also... the pc110's BIOS is used in the
begining of the boot process, but once the linux kernel loads, and begins
to use its native IDE drivers, linux sees the drives according to their physical
ide connections and not their BIOS redirections, and consequently
changes the drive mapping that lilo saw (as it received from BIOS)
(based on your boot order in the easy setup screen)
so, I remap hda and hdb in a parameter to the kernel to be the order
that lilo originally saw.
it took a while to find the params for this 32M flash: 734,4,32
so, my pertinent lilo.conf lines:
boot = /dev/hdb
root = /dev/hdb1
disk = /dev/hda
bios=0x81
disk = /dev/hdb
bios=0x80
append="hdb=734,4,32"
note: lilo and the kernel are both on the same disk, the 32M cflash.
bios is set to boot first from the floppy, then ext cflash (HD2), then the
internal flash (HD1)
I never did get linux to be able to see both the internal flash and the
external cflash at the same time.. I believe I read somewhere that
the kernel stops looking for cflash devices after finding the first one,
but never got around to verifying and/or patching.
Shouldn't matter, but I have kernel 2.2.12 on the box.
hope it helps
