Summary:  add possibility to boot off the DiskOnChip flash device

Original Submission:  This is a request to add a compile time configuration 
option that

would allow to store GRUB bootloader on DiskOnChip flash memory

device and boot off it.



The DiskOnChip flash device is usually available to the system 

via the 8 KiB I/O memory window (chip select mechanism?) and can

be detected by BIOS as an extension device.

What still needs to be done to get this applied? Is the copyright assignment 
not done yet? I know I did my part a long time ago.

Maintenance update of the DiskOnChip NFTL block device layer.



* stage2/disk_io.c: (set_device) update the patch to match the 

current drive number parsing code.  Also extend int to long 

explicitly instead of updating the least significant bytes by

passing their offset (thanks gcc).

* stage2/stage2.c (cmain): Set boot_drive to the drive number

where configuration file was found.  This fixes the menu option

processing when menu.lst is found on a drive different from the

hardcoded one.  The multiple drive boot order is enabled only 

with DiskOnChip, but it doesn't depend on DiskOnChip.

Patch is based on Ilguiz Latypov's <address@hidden> 07-29 patch for DiskOnChip 
support, with the following changes:



a) Added a patch from Karim Yaghmour (address@hidden) that provides a way to 
bypass the DiskOnChip boot entirely, in case Grub is misconfigured or doesn't 
behave as planned. 



b) Added support for DiskOnChip devices formatted with newer versions (5.x) of 
the M-Sys DFORMAT utility. The Grub firmware may now be burned using the 
DFORMAT utility, possibly eliminating many problems that can occur when using 
doc_loadbios under Linux.



c) Backed out requirement for automake 1.6 from previous DiskOnChip patch.  
This patch needs automake 1.5 and autoconf 2.53, like the main GRUB tree.

After testing the GRUB DOC patch I must say that I disagree on the 
fallback/last resort approach for searching for the menu. Personally I think 
this part of the patch does more damage than benefit.

What is needed is a tool to set the menu location, not to have GRUB try to 
guess where it should be.

Other than this having the DOC support in the standard GRUB tree would be great.

a) Apply Mark Meade's unification of DiskOnChip 2000 and 

DiskOnChip Millennium code.  Just as with stage2 or Linux 

MTD DiskOnChip driver,  the stage1 code will determine page 

size by looking at the manufacturer and chip ID numbers.



b) Read chip ID into the stage2 RAM area.



c) Add floppy drive BIOS access as a last resort when looking 

for /boot/grub/menu.lst.

* stage1/doc_stage1.S: Set data transfer direction flag.

Shuffle code to make room in the first 256 bytes.

* stage1/doc_stage1b.S: Shuffle code to make room in the first

256 bytes.

* stage1/doc_stage1.h: Assign 1 not an empty value to the macro

symbol.



* configure.in: Change AS, ASFLAGS to comply with new automake.

* Makefile.am: Likewise.

* stage2/Makefile.am: Likewise.



* README_DiskOnChip:  Add missing files when generating build files.

We are waiting for the copyright being assigned to the FSF.

I'm going to apply the patch, once the copyright problem is

resolved.
