HI again!

Try in BIOS SETUP to auto detect the HD, but use NORMAL
instead of LBA.

This could be needed if the HD is larger then 500mb
and was installed on an old 486 that does not support
LBA. Therefor it could be installed with a software
like OnTrack DiskManager or EZ-Drive.
These installation need the HD to be set as NORMAL in

Verify the jumper settings on HD and CDROM.
If they are connected to the same cable, the
HD should be configured as Master, and CD as Slave.

I have checked the jumper settings and the hd and cdrom are on different cables. I have also have the BIOS set on auto detect.

What you have done is a no-no. Each time you boot up
your operating system (win9x) queries the bios for
hardware parameters. If the systems are similar,
this will cause no problem; if you swap the HDD between
two dissimilar (read 386 to 486, or 486 to 586, or
like that)systems, the drive will no longer boot under the
more advanced CPU. If it was possible to do so, one
could do a basic install to one drive, burn it onto
a cd-rom, and never have to do an install sequece
again. Alas, it is not so. That's what keeps net-
admin people in business :) Start over and use a
boot disk with cd-rom support this time...

I moved the hd from my old P-166 to a Celeron 333 i was building and the hd working fine. I then placed it back in my P-166 and it still wrking without problem and booted the computer several times without fail, then a couple of days ago the bios stopped detecting either of my two hd's or cdrom.
