If you can increase the DMA timings on your motherboard, and this doesn't upset your other cards, you can get a noticable performance improvent. The 1542 defaults to a really safe default transfer rate. You can increase it and run a test to verify. The main problem is the ISA bus, not SCSI. The 1542 tries hard to get around this, but ISA is just a pain. Tom
