The first to observe is at the boot prompt, where you will be presented with a line saying dosdev= 81, biosdrive = 1, unit = 1, maj = 3 (The above figures are for what i would expect wd1 actually being.) It also tells you something like: Booting 1:wd(1,a)/kernel @ 0x100000 Note that both numbers must be 1 for a wd1 disk. Then, see what wd drives are being probed, and whether your wd1 is there. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
