Benedict, Even PCI SCSI cards put their BIOS in upper memory .. unfortunately . it is hard to control where it is going (isn't it wonderful having all of this "smart" technology … pueii). It's basically up to the motherboard how much control you have. To determine if it is a SCSI BIOS problem, try the folllowing: From your original message, this is an add-on to the original system. I would assume that you then have an IDE boot-disk. If so . Great! Disable the SCSI BIOS on the card and drive the HDD thru ASPI. I'm not sure how you do this on a Bus-Logic .. but on an adaptec, you run ASPI?DOS.SYS and then ASPIDISK.SYS in your CONFIG.SYS. Actually, unless you are booting from the SCSI drive, using the BIOS might not be buying you anything. (Actually, under some tests with the Targa2k, I've gotten better performance using ASPI rather than the BIOS). Try that. If the problem goes away and you don't need the BIOS services .. then its solved. If you need the BIOS for some reason or another, then you will have to address the upper memory problem and you will have to use your MB's CMOS to try to controll where the card is going and then exclude from 3DS by using EMM386 or QEMM. If this doesn't fix it, then I'd look again to the I/O and IRQ. Ang, President, Dynamic Technologies, Inc. An Autodesk Systems Center for Multimedia in MD
