Hello,

This is a stupid newbie question.  I recently got NetBSD-1.5.2/alpha
running on a system with a NCR 53c875 and an IBM UltraStar 36G 10k RPM SCSI
drive connected via 68pin connector.  When the system boots up, I see this
output (abridged):

siop0 at pci0 dev 9 function 0: Symbios Logic 53c875 (ultra-wide scsi)
siop0: using on-board RAM
siop0: interrupting at eb164 irq 3
scsibus0 at siop0: 16 targets, 8 luns per target
...
siop0: target 6 using tagged queuing
sd0 at scsibus0 target 6 lun 0: <IBM, DDYS-T36950N, S96H> SCSI3 0/direct fixed
siop0: target 6 using 16bit transfers
siop0: target 6 now synchronous at 20.0Mhz, offset 16
sd0: 35003 MB, 15110 cyl, 12 head, 395 sec, 512 bytes/sect x 71687340 sectors

My question is, does this combination support 80MB/sec, or just 40MB/sec?

thanks,
-bp
