Hi, if you are also annoyed seeing these 'aha(..): DMA beyond end of ISA'
messages when you try to read/write tapes you may want to test my first
guess on bounce buffers for aha1542. You need at least the following:

- I[345]86 PC with ISA bus
- Adaptec 1542C/CF or other scsi adaptor recognized by aha1542 driver
- More than 16 MBytes of memory          (otherwise you don't have the problem)
- A kernel from NetBSD-current    (don't know if patch will work on NetBSD-1.0)

If you are interested, drop me a mail and I will send you a patch.
