    Ray,

    I'm using an Adaptec 2000S, the U160 version of your zero channel RAID
    (ZCR) card, on a Tyan S2468UGN dual Athlon motherboard. It converts my two
    on-board Symbios 53C1010-33 channels to any particular hardware RAID type
    I want. It's currently driving an 18G OS drive and nine 146.8G 10,000 RPM
    drives in a 1.1T RAID5 array. My U160 version is very fast right out of
    the box with no custom tuning.

    The problem is... The new SCSI framework in 2.6 kernels required a
    complete re-write of all SCSI drivers. Some, including the I2O drivers,
    didn't make it into FC2 or FC3t1. There's a work-around for some that
    works, but not for any of the ZCR cards.

    With FC1 being sundowned next month, and RH9 close to (if not at) EOL, I
    found myself in a situation where my only viable long term choice was
    RHEL3. Based on the older 2.4 kernel and SCSI architecture, its dpt_i2o
    driver works very well with ZCR cards.

    If you can hold your breath, FC3t2 could be released in about three weeks,
    and with any luck they'll have the new i2o_proc driver sorted out and
    ready for testing.
