There might be a greater difference with : several disks running together, but it seems like EISA SCSI : didn't make that much difference on my system. Have I configured : it incorrectly or something? What does iozone (avail @ cdrom.com) tell you? It's a disk benchmarker... Is there a difference in the time it takes to load the kernel? Is your drive capable of handling the faster rate that EISA can offer? My SCSI-2 disk will do over 2 megs/sec reads, I am sure. But with my ISA 1542B card, I get 1.2Meg/sec reads and 700k/sec writes. (with a Maxtor 540SL on a DX33 system) A friend with a 1742 & DX66 gets drastically better performance than me with the same drive. Drastic means that I can *see* the differences in times to compile, load X, etc. -- $$ Matthew Deter -- mld@netcom.com $$$$ $$ "Whatever road I take, the guiding star is within me; the guiding $$$$ star and the loadstone which point the way.
