    I need a new motherboard and I have to decide should I buy
    Epox PE-4PCA3+ (and use 3 ATA drives connected to HPT374) or
    Asus P4C800E-Deluxe (and use 1(2) SATA drive and 2(1) ATA drives).

    Board from Asus is about 5% faster in every zone (tomshardware.com)
    but can I make it work?
    In Asus there is unfortunately only 3 ATA connectors (one is needed
    for CD-RW) and I'm not going to put 2 drives on the same cable.

    I understood that there are some problems with promise 20378 used in
    Asus (in 64 bit mode). Is that something I need to worry about?

    Here are chips used in those boards:
     Chipset (both boards):
      Intel 875P + ICH5R

     Asus:
      Promise 20378 raid
      Intel 82547 lan
      Soundmax

     Epox:
      HPT374 raid
      BCM5705 / 5788 lan
      cmi9739A (sounds)

    If network or soundsystem is not working rightaway it's not a problem
    cause I still have working PCI-cards. If disks are working that's enough
    for a while. I'm sure that sound and networks chips will also work on some
    day.

    Asus have also other very interesting board (P4P800-Deluxe) but it uses
    VIA 6410 as a raid controlled and I understood that it's not working (and
    VIA is not going to support opensource.. :( ). With that board I could use
    ATA drives (4 connectors, two of them coming from VIA6410). It would be
    almost as fast as P4C800.

    ps. I'm just an ordinary home user and I don't understand any details.

    Thanks,
    Matti ..with great (but broken) Abit KT7-RAID
