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 detected two problems:
First, the serial ports are not detected. I know that this problem
also happens with other Iwill MBs and some Compaqs. I have found
that two tests made by the sio driver fail (tests numbered 5 and 8).
If I disable both tests, the serial ports are detected and work
fine. However, I would like to know if someone is working on
a patch for this problem. If there isn't any known solution, a
new kernel config option (SIO_PROBLEM, for example) would be
very useful.
The second problem is 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 access to my SCSI disk and CD-ROM without
any problem.
These are the codes on the chip surface:
AIC7880P
AQWA 750
722511
BF3671.1
If the 7880 SCSI controller on my PIILS motherboard is a new
version, or it has any kind of difference, 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,
