Yes, I understand that.  I was after what info would be useful.  You 
gave me a few ideas, thanks. 

As for ACPI, the boot menu option recently changed to "enable ACPI", so 
I'm assuming it must be disabled by default now.  I tried with ACPI on 
6.2-RC1 and got the same result. 

I was able to narrow this down to something that has changed since 
6.2-BETA3.  The BETA3 CD boots, installs, and works fine.  The RC1 CD 
won't boot, as I described in my first message. 

With the em card taken out, the 6.2-RC1 CD boots and installs just fine, 
so it's definitely the em card. 

Dual AMD Athlon MP 2800+, Tyan Tiger MPX motherboard, 2 GB reg ECC RAM, 
Adaptec 2110S PCI-X SCSI RAID, onboard xl(4) NIC, Intel PRO/1000 MT PCI 
desktop adapter (ugh, I know it's not well suited for the box, but this 
is a personal server and a cheap card that's adequate for my needs).  
Drives:  3 x 18 GB SCSI in RAID 5, 1 x 73 GB SCSI on RAID controller but 
a stand alone drive, and a 500 GB IDE drive on the onboard IDE controller.
