Oh, the relevant Intel docs are at: ftp://download.intel.com/design/motherbd/linux/RedHat9_info.pdf It seems that I need to set IDE mode to legacy, where it wont support all controllers, but the following: 1). Pri ATA only 2). Sec ATA only 3). Pri+Sec ATA 4). 2xSATA channels 5). 2xSATA channels + ATA sec 6). 2xSATA channels + ATA pri This means a total of 4 drives tops, as you can see, options 1,2,4 allow 2 drives only, options 3,5,6 allow 4 drives. I will test it, but this BITCH means that I must put the CD/RW burner that is master on the secondary ATA channel on the primary ATA channel as a slave, which means that burning to it will be "very reliable" DOH ! Well, hope someone has some experience with some third party modified drivers that will allow to run in Native rather than Legacy modes with this motherboard (Native allows both ATA controllers and SATA controllers, without using standard IRQ mapping but PCI steering instead). --Ariel > > > Hi, > > > > After playing with it for a while, I decided to turn to the list for > some clues. > > I have on my hands a workstation, based on a Intel Desktop board > D875PBZ (875P chipset), with a Pentium4 2.4C processor.
