Hi Brad,
Your instructions look great -- well written and concise.
One suggestion: the mtd modules in 2.4.18 won't work with any DiskOnChip
devices formatted with newer revisions of the M-Sys DFORMAT utility (5.x or
later). An earlier version (4.2 -- still available at www.m-sys.com) is
needed to insure compatibility with 2.4.18 modules.
The failure occurs when loading the nftl.o module. This issue has been fixed
in newer versions of the DiskOnChip modules.
The DFORMAT command creates one FAT partition by default, so running fdisk
and mkfs.msdos may not be necessary.
Regarding the "mounting twice" problem: I tried this today (with newer
versions of the modules), and it seems to work fine. I'm assuming that
simply mounting the DoC twice, in two different places, is similar to what's
going on in the root.linuxrc script; for instance:
mount /dev/nftla1 /mnt/doc1
mount /dev/nftla2 /mnt/doc2
Also, it's possible to replace the proprietary M-Sys DoC firmware with the
GNU GRUB bootloader. There are two compelling reasons to consider this
option:
1) GNU GRUB is licensed under the GPL
2) The M-Sys firmware takes up considerably more memory than Grub
Disadvantages to this option include the additional steps required to build
and burn the Grub firmware, and also the DoC support is not yet part of the
main Grub source tree.
If anyone is interested, the procedure to do this is documented at:
