We just started to receive the parts for our new NT killer NetBSD server 
and we have hit a snag right off the start. Installing two Adaptec 2940UW 
controllers on different IRQs, one with bios disabled (not the bootable 
one), and one with it enabled (the lower of the two PCI numbers as per the 
adaptec menus) the install hangs.

We are installing from the NetBSD cd-rom which was sold from NetBSD.Com 
earlier this year and it hangs right at the point where it prints biomask, 
ttymask, netmask etc. If we remove the second controller the main 
installation menu pops up. I think the step after this one (masks etc) is 
where the kernel dumps out the root partition information etc. Anyone have 
any ideas whats up ?

Some more info:

Brand new Adaptec 2940-UWs (BIOS V1.3.34 I think, I will gather much more 
detailed info if know one knows about this already)

Hangs with or without hard drives installed on second controller.

Interesting that the kernel probes and finds both controllers and drives 
(if drives are installed on the second controller).

Another interesting thing is I have these controllers and drives programmed 
for 40 MHz but the
kernel probe comes up with 20MHz ???

Haven't had a chance to switch around controllers yet, could be a bad 
controller I guess but I don't think so.

Machine is a new Compaq Prosignia 200 with 96MB RAM, primary IDE controller 
disabled, secondary IDE has CDRom which is found OK.

P.S. On a side note we have a Adaptec 2920C which we hope to install as 
well to run our DAT24x6 changer. Installing it alone (non of the 2940's), 
the Ctrl-A message does not appear. Docs say even if this Ctrl-A banner is 
programmed off hitting Ctrl-A should still work, it does not. The bios chip 
is installed on this card, it is a new card I think. It was lying around 
the office. The card does come up with it's banner saying V3.0 firmware, 
finds the tape drive etc. Is this card supported under V1.3.2 ? I need to 
get the bios turned off on this guy as it is not going to be the boot card 
of the 3 Adaptecs and I think I have to have the bios off on all cards but 
the one to be booted.

P.P.S. PCI Slot 1 seems to be hooked to the onboard E-Net card. The ENet 
card is recognized ok by the kernel. Can this slot be used with say an 
adaptec without worry that they are both using the same IRQ ? No matter 
what IRQ I set the ENet too it changes PCI slot 1 to that IRQ and vice 
versa. Very odd. This slot is not being used related to the problem with 
the dual cards above to simplify troubleshooting.
