Using the DiskOnChip with Linux OS
91-SR-005-10-7L REV. 2.0 6
dformat DiskOnChip formatting utility
dupdate Utility for updating DiskOnChip firmware
docpmap Utility to retrieve information about the DiskOnChip
doc121.ex
b DiskOnChip firmware image. “121” is the firmware version, the actual diskette might
contain higher versions of the firmware, e.g. doc122.exb, doc123.exb, etc.
doc2.fff Alternative firmware image for the DiskOnChip
Note: The file doc2.fff can be found in the \AP012 directory when using DiskOnChip DOS utilities
version 1.21 or higher.
3.2 Linux Driver for DiskOnChip The compressed file driver.tgz contains the following files:
/usr/src/linux/drivers/block/flash_doc/flobj.obj TrueFFS device driver core object file
/usr/src/linux/drivers/block/flash_doc/fldrvlnx.c Source code for driver integration with
kernel
/usr/src/linux/drivers/block/flash_doc/makefile TrueFFS driver’s makefile
/tmp/doc-driver/lilo-patch Patch for Lilo to make pLilo
/tmp/doc-driver/plilo Linux loader, patched to use with the
DiskOnChip
/tmp/doc-driver/lilo.conf Lilo sample configuration file
/tmp/doc-driver/boot.b Boot loader, udpated to use with
DiskOnChip
/tmp/doc-driver/copy2doc Sample scripts, aid tool to create a root file
system
/tmp/doc-driver/pam.d/other File meant only for Redhat & Caldera,
defines permission access
/tmp/doc-driver/samplefs.txt Sample root file system listing
/tmp/doc-driver/doc-patch-2.0.## Patch for kernel sources 2.0.## (only
attached to TrueFFS driver for kernel
versions 2.0.##)
/tmp/doc-driver/doc-patch-example Example patch for kernel sources 2.2.##
(only attached to TrueFFS driver for kernel
versions 2.2.##)
Note: The included patch files are different for the two TrueFFS drivers. When using the TrueFFS driver for kernel
versions 2.2.##, the kernel needs to patched manually and only an example patch file (/tmp/doc-driver/doc-patch-example)
is provided. Refer to appendix III on how to manually patch your kernel.
