I have Abit KT7A-Raid working 100% fine includng the RAID with the following controllers pluged in on it:
- Hercules GeForce256 DDR-DVI
- Aver TV98 TV Tuner
- Pinnacle DV300 - two in one Adaptec 2940UW and IEEE 1394 (Firewire)
- Adaptec 2940 UW SCSI
- Creative Live Platinum
- 3Com 10/100 NIC
- Creative DxR3 DVD decoder
Have in mind that I do noncompressed vodeo on the RAID with 4x75GB IBM HDD's. I have both WinME and Win2000 installed and both work fine with the hardware. I have to confess that the setup of the system took me about 4-5 hours, but since then, already 2 weeks everything seems to be perfect. The RAID controller shares IRQ with the Ethernet card without conflicts. I think that the key to the success with more complicated setups is in using the latest drivers and BIOS versions. If certain order of the controllers doesn't work, just switch their places until they feel good. I think that this is one of the best ABIT's motherboards we've seen so far.
