The system: FreeBSD 2.2-BETA from ftp.freebsd.org around 3 weeks ago, ASUS sp3g mboard with onboard ncr/symbios 53c810. The drive, an IBM DORS 32160 OEM'd for Apple, is on this controller's bus. All bus-type stuff is ok. The problem is that, upon boot, the drive reports itself as a SCSI-I device. The version number of the drive is the same as the one on other people's drives that report as a SCSI-II device. I am getting low performance out of the drive and assume that it is being configured to actually only do SCSI-I because that is what it reports. I did dig through some of the scsi code and noticed a define: SCSI_2_DEF that purported to try to force devices to be SCSI-II at the cost of breaking others. I enabled this, but of course at boot the device is still reporting SCSI-I and I am afraid that the NCR chip is setting up to talk to this device in SCSI-I because of its report at bootup, as my performance has not imporved. Here is my assumption: Apple has changed the firmware on this drive to report SCSI-I. I am assuming the drive can actually be told to do SCSI-II, because totally crippling a perfectly good Ultra SCSI-II device is just too stupid. Can anyone confirm that this may be the problem, that it is fixable, and tell me how? Otherwise I need to send this drive back. I can wade through kernel stuff if I have to, given a few general pointers, if someone can give me a general idea on how to fix this, if possible -- I.E. tell the NCR to talk SCSI-II to the drive no matter what it said on boot. Oh, my NCR SDMS BIOS is v3.0. TIA, Craig.
