No CD-ROM boot from AHA-2940W possible

it.
When I now try to boot from this CD-ROM, eg. Windows 2000 prof., than the
system always reports
Cannot boot from CD - Code 4
I tried also to disconnect my IDE harddrive, but the result is still the
same.
I adusted my BIOS to boot first from
Other Boot Device [SCSI/Onboard ATA Boot Device]
the AHA is adjusted like
Boot target ID = 0
Boot target Lun = 0
BIOS Support for Bootable CD-ROM enabled
Host Adapter BIOS enabled
The AHA detects on ID 0 : Lun 0 --> PLEXTOR CD-ROM PX-40TS
My equipment:
ASUS A7V mainboard
Adaptec AHA-2940/2940W
PLEXTOR CD-ROM PX-40TS
BIOS Award
1. Could anyone tell me, why the machine wouldn't boot from the SCSI CD-ROM?
2. When I select "BIOS Support for Bootable CD-ROM enabled",
than the machine never more boots from my IDE harddisk --> Cannot boot
from CD - Code 4
Why?
Thanks

or higher to fully support BBS according to the release notes:
The BIOS version 1.34 supports the BBS (BIOS BOOT
SPECIFICATION) feature of many newer systems. This allows
your System CMOS to select between IDE drives (if present)
and SCSI drives as the boot device. This feature overcomes
the previous problem of being unable to boot on a SCSI drive
without disabling the IDE drive.
Consult your system documentation to see if this feature is
supported.

I think the last was 1.23.
However cd boot was changed in 1.25 because of a specification change in
the CD boot standard.

Hi, I think it's a motherboard problem. I have the same motherboard with a
Tekram UltraSCSI controller: if I try to boot from a SCSI cdrom the system
hangs after recognizing the cd in the drive.
Is there anyone who has a A7V motherboard with a SCSI controller which boots
from a SCSI CDROM?

Windows 2000 uses a rather uncommon way of booting from CDROM, this
doesn't work on some older Motherboard/SCSI controllers even though
they do boot most other CD's. If it's slightly older than that, it
will not support booting from CD-ROM at all, it's just the ones built
while the specification was still "fluid" that have this problem!
You don't tell us what ADAPTEC BIOS you have, but given that it even
tries to boot from CD-ROM it can't really be a first-generation
adapter (BIOS 1.0 & 1.1x, IIRC none of these has any CD-ROM boot
support).
So if it's really a "plain" 2940W it more or less have to be a second
generation card with EPROM BIOS, with 1.20, 1.21 or 1.23, no later
versions are AFAIK available for this card.
My recollection is that 1.23 has this specific problem, if that's the
case there are nothing you can do to make it boot the Windows 2000 CD
without replacing the card.
It *WILL* work fine in every other respect, so you can boot from
floppies (can be created on another Win95/98/ME/NT/2000 machine, they
are on the 2000 CD) and install from the CD!
If you do have 1.20 or 1.21, note that BIOS version 1.23 is required
by Microsoft for the controller to be "supported" by Windows
2000. Other people have reported problems before they upgraded to
1.23, so it's basically a REQUIRED upgrade.
The same applies to first generation controllers, with 1.0 and 1.1x
BIOS, except that they need to have the latest 1.1x BIOS (1.16)
installed instead.
And it's possible that I remember this wrong, if you have 1.20/1.21 do
try boot from the CD once you've BIOS 1.23 to see if it works...
Note that the 1.16/1.23 BIOS both requires burning an EPROM, the image
are available on Adaptec's page. In case you can't burn EPROM's
yourself and don't know anyone who can do it for you you'd have to ask
Adaptec to provide you with a new EPROM, there are a link for that on
the page I refer to later (no idea if they want money for postage or
the EPROM, you have to ask).
The EPROM images is available from Adaptec, here's the URL for it:
http://www.adaptec.com/support/overview/aha2940.html
Here's a link to Microsoft's statement with regards to minimum
required BIOS levels required for early Adaptec controllers:

This is unlikely to be the same problem, the original poster had an
old Adaptec controller. These are known to have trouble to boot from
the Windows 2000 CD, regardless of what motherboard you have, in fact
I think there are no version of the BIOS for his card that can handle
that CD!
>Is there anyone who has a A7V motherboard with a SCSI controller

I've done that on several A7V, works perfectly fine here (both Windows
2000, 98 and Linux)... Mainly from booting from Tekram 390U2W
controllers, but I've also seen it work with Adaptec cards, cards
which are newer.
I'm afraid you have to look elsewhere, what CD's have tried booting
from, Windows 2000 uses a different booting method from most other
bootable CD's (I think WinNT 4 might use the same method, but I'm not
sure).
Without a lot more details on your setup it's not much anyone can do
to help you with your problem.
Wolfgang
Yes, the BIOS version 1.23.
I think I'll replace the SCSI card with a newer one.
Thanks again

Most likely not. But the 2.57.2 version can be made to work (patched) with that
card if you are able to burn an Eprom.
The procedure is in http://www.scsifaq.org/scsifaq.html#Host_Adapter2
(or ask me for the image)

Do you know if this really works with this kind of early cards, the
procedure seems to be aimed at installing BIOS on cards which simply
have the wrong PnP ID (due to being OEM cards) but is otherwise
identical to cards that can take that specific BIOS version...
Given that there are two different 1.23 EPROM images for the second
generation cards, and that first-generation cards doesn't support even
1.2x BIOS it's certainly possible that newer BIOS don't support early
cards at all.
It's certainly possible that it will work, but unless someone has
actually tried this I think it's a bit premature to say that it WILL
work.
It might be fun to try it, but while I should have no trouble getting
my hands on Adaptec 2940's with 1.2x EPROM BIOS to try it out on I
don't have a burner to test it with any longer...
I could probably solve that if it was important, but the Tekram I
*prefer* to use don't have that problem :-)

from an ATAPI CDROM on the same system, so the boot process works).
TL> Without a lot more details on your setup it's not much anyone can do

I have the following configuration:
A7V Motherboard rev 1.02 with bios 1.004
Controller UltraSCSI Tekram DC-395 bios 3.03 (the last one)
Scsi chain: Teac CD recorder CDR55S
Plextor Ultraplex40X CDROM
HD IBM 307030 UltraATA100
I have tried all the 1.004* bioses and the last beta for the motherboard
without results. The HD is connected on the Promise controller (I have
also tried to connect it at the Via ATA66 controller). I have enabled the bios
option of the motherboard to boot from SCSI (and the SCSI has higher priority
on the ATA100 devices). I have also enabled the boot from CDROM option on the
SCSI controller. When I insert the bootable CD in the drive the system
recognizes it and asks me to select a section which to boot from: I select the
only available section, then the screen clear and the boot process hangs (so I
have to reset). Before the system hangs, I don't see activity on the SCSI
chain.
Thanks in advance for any help!!

Fabio
