PC BIOS sucks, but the problem you are having hasn't been on any system I've
bought in the last 5 years.

It really sounds like you got a buggy BIOS. Have you tried to find an updated
BIOS and flash that?

It could even be a bug with IDE that the BIOS just can't handle, triggered by
a different drive.

Well, I have to admit now that I've thought about it more, some of it was
about trouble with SunOS and Solaris, not the ROMs, and ESDI and ESDI bridged
drives. I used to hate Sun's disk setup. Actually I still do, but I just
rarely have to use it now that NetBSD is my primary OS.

However, there were also issues with ROM and SCSI, and the units I remember
most were Sun SPARC towers (the VMEbus systems), Sun SS1 and SS2, and my
current Sun SS5.

The symptoms:

The Sun would see the drive, but not the right model or capacity.

The Sun would see the drive, but was unable to boot from it and/or I could not
install the OS.

In all of these cases, a convienient Mac or PC was able to see and use the
drives just fine (except for ESDI, which I never used outside of Sun systems).

The SS5 generally just works, but I did have a drive once that it never saw as
the correct drive, and I had trouble installing an OS on it.  I gave up
trying to figure it out and got a pair of IBM 9GB drives which work

The largest drive I have tried on the SS5 is an 18GB Fujitsu, and it
also works fine.

I never had a Sun wedge either.  Just problems seeing/using particular

I didn't mean to imply the Sun crashed.
