b

contain higher versions of the firmware, e.g. doc122.exb, doc123.exb, etc.

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.
