DOS tools work! great stuff again ldotsfan
I took a stock drive, unlocked it on my chipped machine and put i on the master IDE.
I set up a dual boot on USB using grub4dos which boots xboxhdm2 & FreeDOS.
I booted FreeDOS & successfully locked**, unlocked & disabled the HDD using the DOS locking commands. After locking, i rebooted back to FreeDOS (<1 min) and predictably reported errors on trying to read HDD. I then unlocked the drive easily using the master password. I then disabled the locking using hddisab command (btw - that's different as to what's in your earlier instructions which was hdddisabl).
This means as long as you know the password - theres no need to wait 10+ mins to unlock via xboxhdm/hdparm - DOS it in less than 1 min
I then tested xboxhdm2 on the USB boot partition. It booted perfectly with the unlocked/disabled drive. I tried to lock using the inbuilt tools but failed. I seen a new line in the locking screen 'master password revision code = 32769). Have i permanently disabled locking on this drive?
I am pretty confident that the dual boot method works. If there is any demand and as long as Anny agrees (his work), we will make available a customised download for others to test/use.
** i used XBOXSCENE as the master password. It however reported that my password was set to XBOXSCENE0 (that's a zero). I ignored the zero when unlocking it and just typed in XBOXSCENE and it worked fine.
