Hi Rafal,

Well I tried the grub 0.97 patches. I recompiled grub with both patches, then
replaced the etch grub withthe new .deb. Then re-installed grub stages on the
disk with
grub> root (hd0,0)
grub> setup (hd0)

Now if I reboot the machine at at the live grub prompt, I do a displaymem,
it says:

EISA Memory BIOS Interface is present
Address Map BIOS Interface is present
Lower memory: 631K, Upper memory (to first chipset hole): 3144640K

There are no address ranges given.
So it looks like it only sees 3 GB.

If I run grub from the booted system, on the command line, it gives the ranges,
and also the debug info from the patched version of grub.

# grub
Probing devices to guess BIOS drives. This may take a long time.
SMAP: addr:f7b4fc00 cont:1
SMAP: addr:f7b4fc18 cont:2
SMAP: addr:f7b4fc30 cont:0
mbi.mmap_length: 48


   GNU GRUB  version 0.97  (640K lower / 3072K upper memory)

      [ Minimal BASH-like line editing is supported.   For
        the   first   word,  TAB  lists  possible  command
        completions.  Anywhere else TAB lists the possible
        completions of a device/filename. ]
grub> displaymem

     Length:   0x0 X 4GB + 0x60000 bytes
  Usable RAM:  Base Address:  0x0 X 4GB + 0x100000,
     Length:   0x0 X 4GB + 0x300000 bytes
grub>


any ideas on where to go from here?
Is it normal for it to only show
Upper memory (to first chipset hole): 3144640K
at the grub boot menu?

Thanks
