two drives
 

Installing Caldera...master drive has WIN98. Can I make the
slave drive Caldera? Easily? Some bugs? No way?

Easily. Just format it with linux native partition, or journal, install Caldera on it and install LILO or GRUB to be able to boot into linux and windows.

it generally easier and safer to put linjux on the master, and windows on the slave, and lie to winodws about where it is when you load it. this way you NEVER need to touch anything at all on the windows drive, and sim[ply need to remove the linux drive and put windows back on master, and you'd have never known linux was there in the first place.

you just need to add a section saying

other=/dev/hdb1
label=windows
table=/dev/hdb
map-drive=0x80
to=0x81
map-drive=0x81
to=0x80

to the lilo.conf file
