SubjectFlashdisk, M-Systems, Devicedriver, TrueFFS, Booting
Hi,

i have a M-Systems Flashdisk PCD-896 (ISA) with 4 MB. With an
BIOS-Extension and TrueFFS it's possible to access the disk
like an normal harddisk (realtime stuff under DOS)...

I like to boot a very small linux from that Flashdisk into RAM. But after
switching to protected-mode i need a kernel-driver, or?

I searched for a kernel-driver for this hardware, but i didn't found any.
But in devices.txt i found this:

 31 block	ROM/flash memory card
		  0 = /dev/rom0		First ROM card (rw)
		      ...
		  7 = /dev/rom7		Eighth ROM card (rw)
		  8 = /dev/rrom0	First ROM card (ro)
		      ...
		 15 = /dev/rrom7	Eighth ROM card (ro)
		 16 = /dev/flash0	First flash memory card (rw)
		      ...
		 23 = /dev/flash7	Eighth flash memory card (rw)
		 24 = /dev/rflash0	First flash memory card (ro)
		      ...
		 31 = /dev/rflash7	Eighth flash memory card (ro)

		The read-write (rw) devices support back-caching
		written data in RAM, as well as writing to flash RAM
		devices.  The read-only devices (ro) support reading
		only.

 90 char	Memory Technology Device (RAM, ROM, Flash)
		  0 = /dev/mtd0		First MTD (rw)
		  1 = /dev/mtdr0	First MTD (ro)
		    ...
		 30 = /dev/mtd15	16th MTD (rw)
		 31 = /dev/mtdr15	16th MTD (ro)

But where can i get informations about these drivers??? The statement in 
devices.txt "I do not have any information about these devices beyond
what appears on this list.  Any such information requests will be deleted
without reply." isn't very helpful!

Is there a list with device-driver projects?

Thanks for any help!

Greetings
