(dont worry about the firmware part yet) I created a bootable floppy with xtreme boot maker.
So then, i rebooted my pc, hooked up the xbox drive to sata, and did the following
For ms28 firmware versions of drive you will need to use the Vcc method or the VIA SATA 10 sec method to read/write flash.
Advisable to make a backup of your dvd drive firmware first.("mtkflash r /m orig.bin")
In Windows, copy orig.bin to same directory as this release (same directory as ReadMe.txt and X360SAM.exe)
Double click "Make Xtreme firmware.cmd" and follow the prompts. Thanks to eXOBeX for X360SAM.EXE
Copy x53x.bin to boot disk where x is a,b,c or d.
Power off PC
Plug SATA cable from DVD drive to PC. Power cable drive still connected to Xbox 360
Power on Xbox 360
Power on PC
Boot with standard dos boot disk with included mtkflash utility
Run "mtkflash w /m x53x.bin.bin" where x is a,b,c or d.
my motherboard is an abit fatal1ty AA8XE, works just fine so far.
