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.

Please help.

Are you using USB or NTFS DOS boot disc ? to retreive the orig.bin firmware.
Have you backed up the original firmware on any drives yet?

Could be a chipset problem aswell? Are you using textbooks tutorial?

I cant even get to the point of backing it up. Thas tha I am trying to goI type (SAMREAD 1234567 12345)

Once again how are you trying to back it up? With an NTFS DOS boot disc or USB or what? Which method are you using it would seem you still have a lot of drives connected if all those are showing up.
What tutorial are you using?

I am trying to back it up with the bootmaker. you type samread then i backs it up. Am i suposed to unplug all my drives. I dont know what tutorial.

I'd suggest you go and find textbook tutorial here. TEXTBOOK
Read it it will make it all clear. Use the NTFS DOS approach.
Sounds like you better read it good, otherwise you will have dead 360's.

thats basicialy what i got but it sounds like I have to have the VIA for the ms28. Is that correct the VIA is the only one that can do the ms28 without soldering?

is the VIA 6421 the best one or what

If you read the tutorial it would have said this.
This link is in the tutorial and thats what is says there. So make up your own mind.
