You didn't say, but this configuration works under something? Even Windows? Is there a BIOS SCSI probe utility? One where you can list devices? The P6NP5 manual acts like it contains the SC-200 manual too. Says there is an "auto NCR BIOS" setting, offering the ability to use a BIOS on the card (which the less expensive cards lack) or the same built into the MB BIOS. You might check this. Also consider flashing your BIOS to whatever current version is available. I too have a P6NP5 PPro system. New out of the box it did the darndest things. Floppy drive was flakey under FreeBSD but worked under DOS. Fought it for weeks. Then on a lark in the BIOS setup I hit "restore to factory defaults" then punched selected things back to where I wanted them. System has purred like a kitten ever since. Forgot when this was. Seems like the P-II 266 was just out. I'm running a PPro-166/512k, (now) overclocked to 210. The conclusion is there are hardware parameters that can be set in the BIOS BBRAM that do not have an interface for changing in the BIOS setup program. Parameters that apparently Microsoft knows about and is able to put into sane state after boot. And while we are at it, this BIOS allows you control over IRQ assignments. I don't remember why but I have my SC-875 on IRQ 11 all by itself with all the rest of my PCI stuff (including an old 2940) mux'ed on IRQ 15. Then again it works and no reason to change it. -- 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.
