>Description:
I'm trying to install from SCSI CDROM. Host controller
is the Adaptec 2940UW - SCSI BIOS rev is 1.22S.

I've tried three different release CD's, 2.2.7,
3.1, and 3.4, and they all have the same behavior:
they freeze during boot, before even any diagnostics
are printed (i.e. freezes during "spinning wheel").

I've read about the install problems with newer 2940
BIOS revs, but haven't heard a solution.

My system is a Dell XPS Pro200n, PPro 200MHz, 64MB
EDO DRAM. CDROM is a Plextor 8X.

>How-To-Repeat:
Boot system with disk1 of 2.2.7, 3.2, or 3.4 RELEASE
bootable CD.

 I just installed 4.0 on a system with an Adaptec 2940U with BIOS v1.23.
 It booted from CD, but BSD's probe didn't detect the CD-ROM drive (cd0),
 even though it found the two SCSI disks on the same controller (da0 and
 da1).  Booting from floppy didn't help.  My workaround was to put the CD
 in another computer (running Linux) and export it via NFS, and install
 over NFS.  I'm using an Epox Athlon motherboard.  Once BSD was
 installed, it found the CD-ROM drive (a Yamaha CRW4416S CD-RW) and I can
 use it without problems (I'm using the generic kernel).
 
 So, maybe this is a little progress, or maybe my motherboard or Adaptec
 BIOS version just let it get a little farther.
 
 What happens if you mount the CD under another OS and make floppies from
 floppies/kern.flp and floppies/mfsroot.flp, and boot from them--does it
 still freeze?  Can you remove the SCSI controller and try it, or is it
 integrated into the motherboard?  (You might not have any hard disks at
 that point, but it would show whether the SCSI controller was the reason
 for it freezing up.)
