Change MBR on a 64MB CF media

NTFSD
1

Hi,

I’m new to this subject so please bare with me.

I have a CF media connected via IDE to a PC. The media is mounted as E:
Under XP I want to do a “Format /s” on this media: Change the MBR and copy some DOS
files to make this media DOS bootable.
How can I change the MBR of a CF media ?
What can be a good starting point to handle this challenge ?
I’m aware there are utilities like the “HP format tool”.
But I’m looking for a command prompt utility that will do the job.
Are there any books on this subject ?

I have some experience with developing WDF device drivers for PCI based modules.
Should I develope a device driver for the above purpose ?

Thanks.

Hi Zvi,
no need to develop any drivers.
Just leverage your experience with gnu and opensource.
See any Windows port of “dd” for how to write to disk sectors directly.

CreateFile Function :

IIRC, there was also some opensource DOS clone, from which you can borrow
format.

Good luck,

try
sys e:\
After formatting the drive e:.

Hi,

What is "sys e:" ?

I tried it on windows XP and got " \sys’ is not recognized as an internal or external …".

Thanks.

Sys was a DOS command that transferred the system files to a disk. I doubt
that it exists on Windows.

Good luck,
