This is a system which has me reconsidering the wisdom of SCSI for my needs: CPU: Pentium III/Pentium III Xeon/Celeron (501.14-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x673 Stepping = 3 Features=0x383f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT, PSE36,MMX,FXSR,XMM> real memory = 134201344 (131056K bytes) avail memory = 127221760 (124240K bytes) [...] ad0: 14649MB <IBM-DTLA-307015> [29765/16/63] at ata0-master using UDMA33 Have seen bonnie report over 22 MB/sec on that drive and system. Then again this second one is almost sad enough to be funny.

Well, last I tried RELENG_4 on the above 5x86 it tried to do busmaster on the IDE interface but timed out and fell back to polled mode. That was better than the first time I tried 4.0-R and it blew up. Later read there was a conflict between ISA ed0 and the new ata code. Splurged on the purchase of a DEC 21140 based 10/100 PCI card for $12 and cured that problem. If you say it might work now (its a UMC chipset) then I'll give it a shot. -- 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.
