I am trying to flash 2 dives ms28 and ms25. I am using an xtreamboot maker. I select the 52a-ms25 FW. then in the MTKflash bar I have 6 choices. SiS PCI IDE, Primary IDE Channel, Secondary IDE Channel, SiS 180 RAID controller, Promise technology inc. Ultra IDE Controller, or VAX347S SCSI Controller. Not sure which to pick? I have been trying the SiS 180. I boot up then in the commands and I get this. Primary Master, Primary Slave, Secondary Master, Xtream master, Xtream slave, IDE master, IDE slave. I have tried all of the multiple times and can seem to get it to read.
