Dear Masters,
We have a problem about our Windows NT System. We are trying to setup some new PC's and using the SCSI disk image of existing computers since we dont have the setup files for some special industrial programs running on the system. There are a Adaptec 39160 SCSI Host Controller for the SCSI disk and 2 Adaptec AVA-2906 SCSI host adapters on the system. We have old AVA-2906 cards and new purchased AVA-2906 cards. The new system with the disk image of the original system is running properly with old 2906 SCSI adapters, but giving the following error on blue screen while trying to boot Windows NT with new 2906 SCSI adapters.

STOP:0X000000A (0x00000004, 0X00000012, 0X00000000, 0x80393F6E)
IRQL_NOT_LESS_OR_EQUAL address 80393f6e has base at 8038c000 - aic78xx.sys

This aic78xx.sys is the driver of the AVA-2906 boards. We removed and re-installed the driver of the AVA-2906 cards, although it was already installed on the disk image. And this didnt solve the issue. These AVA-2906 SCSI adapters are connected to Data Peripherals from an imaging system.

We have 60 new AVA-2906 boards, and tested all, none of them are working. I think that; this surely elimintaes the possibility of having hardware problem with the cards; since all of them cannot be faulty.

I am looking for you help..

Can you boot the systems without the AVA-2906 controllers installed in the machine?

If you can, remove the aic78xx.sys file along with the accompanying inf file.

Once you can boot the system, replace one AVA-2906 card in the system. Using the updated drivers from the Adaptec website, try installing the drivers in the system.

If you once again get the blue screen once the driver is installed, you may have to force that specific pci slot to use a specific IRQ. This will be done in the bios of the machine.

You may also want to try setting the bios to NON-PNP operating system and boot again. That may be enough to get the system up and running on the available interrupts in the system.

Hope this helps,
