Ricardo,
The problem is very possibly in the fact that when you put the CF in your
PC110, it is not /dev/hdc, but rather /dev/hdb. The bios=0x80 is the right
direction, if I remember correctly, but it probably needs to be bios=0x81, to
signify that /dev/hdc will be the second drive... Try that.
And to possibly ward off the next problem you will have, linux-2.0.x and
most of linux-2.1.x don't support two flash drives... Once you get the kernel
loaded and uncompressed, you will find that hda (the internal 4Mb flash) is
detected, but the 45Mb CF is not. To fix, you need to look for 'SunDisk' in
the ide-disk driver (drivers/block/ide-disk.c) and comment out the

if ( ...='S' ...='u'...) ... continue

lines. Then you will probably also have to supply the geometry to lilo with
append="hdb=<cylinders>,<heads>,<sectors>". I have a 48Mb CF, and the C/H/S
that I use is 734/4/32. Good luck.

-Craig
