Why is my mda2's EXTENDED ROM read only :-(

[deckard]

Hallo,

I want to tune up my german mda2's extended rom also.
But i can't . It's read only!
Can't delete,write,rename.
I only can make it visible thats it.
Please help!

Edit:
It seems that the disk on chip (doc) can be write protect by software.
Look here:

There is an entry in the windows registry called TrueFFS.
(True Flash File System).You have too search the registry for trueffs.dll
I would be interested for some dwords values from other people whos rom is not protected.
For instance the key "Ioctl" has an value of 4 in my mda2.
This is my TRUEFFS Registry Area:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\TrueFFS]
"Profile"="TRUEFFS_DOC"
"Index"=dword:00000001
"Dll"="TrueFFS.dll"
"Prefix"="DSK"
"Order"=dword:00000000
"Ioctl"=dword:00000004
"WindowBase"=dword:04000000
"DeviceArrayIndex"=dword:00000000
"IClass" =hex(7):7B,00,41,00,34,00,45,00,37,00,45,00,44,00,
44,00,41,00,2D,00,45,00,35,\
