The latter way has the > advantage not to require a screw-driver :). Asus MB's (sample size: 1 PPro, 1 P-III) like to share one free IRQ for all PCI cards. And it works. Usually IRQ 11 unless the 2nd IDE/ATA is disabled then 15 is used. Mandatory SCSI content: I haven't found a soft way to alter boot order when there is more than one SCSI card installed. I always guess exactly wrong and have to take it apart and swap the cards or cables. The one thing I can do is with the onboard Adaptec SCSI, can force it to be last, or default to first, from tbe BIOS setup. Is it safe to share an IRQ between, say, a SCSI card and the onboard "PCI" ATA stuff? If so, then why do they use both IRQs 14 and 15? -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
