no problem. invoking of the LBA is automatic, and is used when formating 
a new disk, but stick a non-translated disk into an LBA-BIOS system, and 
it will see it just fine. I moved the 1.1GB disk I mentioned to a DX4 
with LBA and it was as smooth as a baby's.... smooth part.. you know.

none at all. they both see the disk fine, only DOS will see onl the 
disk's beginning.

well, I don't like LILO that much, because it sits on the MBR, and 
reconfiguring is hell, and tracing back a step from a faulty kernel often 
means a bootdisk is needed. I always use LOADLIN from the DOS commandline 
or config.sys (DOS >6 has a menu feature). the nice thing about Loadlin, 
is that the kernel image(s) sit on the DOS partition, and can therefore be 
seen by the BIOS anyway, and after loading it can mount the root even 
from cylinder 2000 if needed. LILO uses the BIOS and so vmlinuz (and maybe 
also /root) should be under 1024 cylinders. This didn't bother me when I 
started using LILO though on the old disk: 1024 cylinders are 528 meg for 
DOS, but I formatted it under 512 meg anyway to gain the smaller 
allocation units (and so actually GAIN free space), and so I got the 
needed space for LILO as a giveaway.

should I look for something in IL-ADS? or will you go and buy a propper 
Pentium board?
