Apollo Pro 133A (Dual) question

[kmmatney]

We have a few "industrial" pcs at my work, using the Apollo pro 133A with dual pentium 1.0 GHz cpus.

We have been getting BSODs in several systems, most running Windows NT 4.0. No VIA 4-1 service packs have been installed.

When you look at the VIA website, WIndows NT is not listed in the 4-1 list of operating systems. In fact, only the IDE miniport driver seems to be updated.

Does anyone know if the 4-1 drivers are necessary when running Windows NT 4? The computer has 5-6 additional cards installed, with 2 ISA cards, and 3-4 additional PCI cards.

I looked up the BSOD message on the internet and found out that it may have something to do with IRQ 2.

Got bluescreens? Check RAM, CPU cooling and power supplies.

www.memtest86.com for the best RAM test around. Takes hours to complete, definitely worth it.

The reason why you don't install 4-in-1 drivers in NT is that NT doesn't support AGP anyway, so actually the IDE driver is about the only useful thing to install.

IRQ2? Definitely bs. IRQ2 is used in all ATs to cascade from interrupt controller #2 (handling IRQ8 to 15) to #1. This is a southbridge internal signal, no programmabilities, nothing to screw up here, not even if you try.
