I've new DC-390F (NCR53C875) SCSI controller, and relative
hdd SCSI Quantum Fireball 3.1Gb.
I want know the correct configuration.
This is the boot text on Linux 2.1.30:

testing it with hdparm:
# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 16 MB in 5.18 seconds = 3.09 MB/sec
# hdparm -T /dev/sda
/dev/sda:
Timing buffer-cache reads: 32 MB in 1.09 seconds =29.36 MB/sec
I've only ~3 Mb/s of transfer rate ? It's possible ? My previous
HDD have ~4.7 Mb/s on a Triton III controller! What I wrong ?
Thanks!
