installation hangs during (after?) downloading scsi stuff on P133

Yes, I experienced the same (using AHA2940AU). No, Installing / Not
installing the SCSI BIOS appeared to make no difference. My guess is
that the SCSI code in the generic kernel is trying to cope with too many
different card types, and screwing over the 2940. In my case, the 2940
is an AU, not wide; which might be making things worse. Neither of you
mention whether you're using a wide card or not.
I solved things simply by taking out the card for the install, compiling
a custom kernel, and everything runs fine[*]. Jim, this should work for
you. Anders, I guess you'll have to pre-compile, since I guess the SCSI
drive is the only one. I'm afraid I can offer no advice about making
install kernels. Suffice that I tried the alternate rescue images, to
[*] Actually, not all is fine. Jim, this may particularly affect you; I
have 3 devices: CD-ROM (Plextor 40TSi), CD-RW (Plextor PX-4220Ti), and
DVD-RAM (Panasonic LF-D101E). Use of the CD-RW caused SCSI Resets after
about 100M transferred, which naturally toasted me a coaster, and the
reset never succeeded --- it was a reboot job. Turning off the BIOS
Installation on the card sorted this problem; I know not why...
On a sideline note, if anyone has got cdrdao working on a PX-4220Ti, I'd
like to know how. Come to that, just success with cdrdao would be of
interest. Everything it writes is readable only by the CD-RW, which is
of limited benefit...
