- I tried once a long time back to set the DMA transfer rate on my Adaptec
- 1542B to 10 Mb/s, and it hung the system. I was able to get it to work
- reliably at 5.7 Mb/s instead of the default 5.0 Mb/s.
-
- I would like to know if there is anyone running the 1542B at its full speed
- of 10 Mb/s on an ISA bus? How can this be done?
-
- Thanks. Please use e-mail. I'll summarize.
