Hmm, how come my new P6NP5 with P6-200 and 96MB RAM (parity mode) can
give me only about:

>> dd if=/dev/zero of=/dev/null bs=1m count=1000
1000+0 records in
1000+0 records out
1048576000 bytes transferred in 18.359226 secs (57114390 bytes/sec)

I tried fiddling with the "RAS precharge" and "RAS to CAS delay" in
the BIOS setups but the numbers hardly changed (always between 57MB/s
and 60MB/s).

Did I get a "first generation" 440FX or something? ;(
