Hey, sorry for my previous stuipidity.. here's my problem..

The Tekram BIOS says the drive is 80Mb/sec wide, which it is (IBM UltraStar
9ES)

here's an output from FreeBSD 3.2-STABLE (8/5/99)

ncr0: <ncr 53c895 fast40 wide scsi> rev 0x01 int a irq 11 on pci0.19.0 
..
da1 at ncr0 bus 0 target 6 lun 0
da1: <IBM DDRS-39130D DC1B> Fixed Direct Access SCSI-2 device
da1: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing
Enabled
da1: 8715MB (17850000 512 byte sectors: 255H 63S/T 1111C)
...

It is connected to the "J1" connector which is 68-pin 16-bit WIDE Ultra2
internal SCSI connector, via a twisted-pair cable with the Ultra2 LVD
terminator, supplied with the controller, at the end..

why is FreeBSD only saying 40Mb/sec, 20Mhz? I was told you need 40Mhz in
order to obtain the 80Mb/sec transfer rate.. which FreeBSD only says
40Mb/sec.. what is with this picture? 

Please reply to me directly as I am not subscribed to this list.

Thanks,

Kevin
