- Would you like to be more specific about your experiences? The newest
- CPU boards that I've seen have all been compatible with the Adaptec 1542B
- without any problems, and I use a wide variety of completely generic
- boards with various chipsets. Some of them even have the BIOS chips
- soldered in place - a practice I object to, but realistically, probably
- increases reliability when the BIOS code is mature. DMA is built into
- most of the LSI chipsets, so it ought to be easy for you to pinpoint
- the ones that have problems.
