erase_all /dev/mtd0
doc_loadbios /dev/mtd0 grub_firmware

Ilguiz,

Is the "erase_all" necessary? Does this delete the Bad Block Table on the DoC 2000 or Millennuim?

I was able to get a Millennium booting without any "erase_all" commands. I guess I'm not clear on why this is needed.

Thanks,

Mark

I agree erase_all is dangerous because it will delete the bad block table. The smarter way of inactivating the NFTL driver would be obfuscating the NFTL headers or implementing the previously mentioned ioctl() interface to NFTL layer or relying on the M-Sys native MS-DOS based NFTL format utility.

I was afraid that the NFTL driver would keep updating the /dev/mtd0 device even when nftl_format was running.

Best regards,

Ilguiz
