IBM PC730/PC750 - 3270 card fails with Matrox video adapter
Applicable to: World-Wide
Symptom :
A 3270 Communications adapter may fail to function in an IBM PC 700 Series 6875 or 6885 system with a Matrox Millennium PCI video adapter installed.
Problem Isolation Aids :
The Matrox Millennium PCI video adapter may conflict with the fixed IRQ requirements of the 3270 adapter (IRQ 2). The Matrox adapter may default to IRQ 9 which is equivalent to IRQ 2 (IRQ 2 & 9 are cascading interrupts).
Fix :
Obtain and install Flash BIOS level N1JT84A or higher. This update will allow the system to reroute the video adapter IRQ requirements to an available ISA IRQ.
