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.
