The above error is an irq sharing problem, but I thought it only occured with non plug and play oses such as nt4. I recieved it under nt4, pci3 shares its busmastering and irq with the hpt366. Both highpoint and symbios when contacted told me that thier devices share irqs, supposedly there are only problems with shared irqs under non plug and play oses, but I received problems under windows 98 as well. Needless to say I can't get the scsi card to work in any slot now, and I have to leave slot 3 empty because I have yet to find a device that will share with the hpt366 successfully.
