index | next in thread | raw e-mail
Hello,
I have just purchased a new system for running FreeBSD. It is
based on the Iwill PIILS motherboard, which uses the 440LX
chipset and includes an Adaptec 7880 SCSI controller.
I'm running FreeBSD-stable now, but I have found a problem
related to SCSI:
When the AHC driver tries to read the 7880's SEEPROM, the operation
fails with a "cheksum error". I'm afraid that the 7880 chip on my
PIILS motherboard is different (perhaps another version?): for
example, I cannot choose the termination type using the Adaptec
SCSI BIOS ("High ON/Low ON", "High ON/Low Off"...); instead, I can
only select "Enable" or "Disable". However, the "cheksum error"
trying to read the 7880's SEEPROM does not prevent the AHC driver
from working properly. Until now, I can use both the SCSI disk and
CD-ROM without any problem.
The version of the SCSISelect utility is 1.26S2. The BIOS is Award,
version 4.51PG. And these are the codes on the 7880 chip:
AIC7880P
AQWA 750
722511
BF3671.1
I'm ready to make any tests on my system; however, in this case
I will need some help from the person(s) responsible of the AHC
driver.
Cheers,
-- JM
