Hi, Peter!

TM>>Bus-mastering will work, but the memory above 16 MB is only used for

Uh-oh... VERY off-topic. But I'll answer this in the echo because I don't
know if net mail will get through to you. If you've still questions, try it
via net mail, though.

PH>I have a basic ISA

The German OS/2 FAQ states that OS/2 will not use more than 16 MB memory if
you have an ISA board with a bus-mastering device plugged into it. This
includes some SCSI controllers and network cards... In this case, all memory
above 16 MB is used as an extension to the swap file. This is still better
than swapping to disk! I don't know about LocalBus bus-mastering (if it
exists, anyway), but with EISA bus-master devices this problem does not
occur.

So the memory range above 16 MB is *used* in all cases, but not necessarily
as conventional memory...

Bye,
Thomas
