<LOL>
duhhhh, wha..??
okok, i read this and FWIW until i see the note on the IBM site, in my
experience, the 5.1gig, 17mm HDD was a solid drive..
very few problems..
i may take a 5.1gig in, in trade, and if i DO i'll try loading some stuff on
it.. including the 770Z preload, and, maybe, a 770-1AU preload..
be sure the machines bios is up to date, and set the CD to be bootable, thus: 1.
Floppy, 2. CD, 3. HDD...
for now, look to win2000 RC2 for the kilnking and settings for the recovery CD
problems..
