Uh, something in the MB BIOS (it was a dual P-II Asus MB with one P-II and onboard Adaptec, P-somthing-97-with-an-S-somewhere) recognized the Asus SC875 well enough to lock up the entire system in boot. Part of the problem (I now recognize) was some NCR/Symbios BIOS's have fits if a HD is not on their bus at boot time. Tried the above with nothing. And with Seagate Scorpion DDS-3 drives. Seems the last message printed to the screen was, "^C for BIOS Setup". New BIOS flashed into the SC875's (there were two in this system) cured my booting problems. Now I'm thinking the sa driver or something is performing reliably but something about the 3.1 scheduler, buffering, or the lack of buffering, is causing performance to be less than what the hardware is capable of. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
