Supermicro X5DAL-TG2 Motherboard Hard Drive Support Question

Their site says: "Dual EIDE ports support Ultra DMA 100MB/s of Burst data
transfer rate, supports UDMA Mode 5, PIO Mode 4 and ATA/100"

See: http://www.supermicro.com/PRODUCT/Mo.../X5DAL-TG2.htm

Does this mean two sets of master/slave or one? I'm thinking only one set of
master/slave.

It also says: "2 Silicon Image controllers support 4-port Serial ATA ( RAID
0, 1)".

I don't know squat about SATA, but I'm guessing it's not backwards
compatible with Ultra DMA 100 or Ultra DMA 133, no?

I have four 120 GB hard drives, two 100s and two 133s. I do have a PCI RAID
controller that I could use with them and it's supposed to be bootable, but
ya never know until you try.

Should I buy an SATA disk to install Win 2K Server onto and leave the UDMAs
on the RAID controller?

Will I need to buy another UDMA controller for my other EIDE devices? (CDRW,
DVD +/-RW)

I'd appreciate any insight.

Thanks much,

Dave
