Ditto. This is a system which has me reconsidering the wisdom of SCSI =

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. OTOH it is
reliable:

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.

The human mind ordinarily operates at only ten percent of its
capacity -- the rest is overhead for the operating system.
