I have simple question: is it possible to get all memory available for Linux
system when GRUB is used ?
Here is details:
GRUB says:
-- cut --
GRUB version 0.5.94 (639K lower / 13312K upper memory)
-- cut --
but then displaymem shows:
-- cut --
grub> displaymem
Address Map BIOS Interface is present
Lower memory: 639K, Upper memory (to first chipset hole): 13312K
[Address Range Descriptor entries immediately follow (values are 64-bit)]
Usable RAM: Base Address: 0x0 X 4GB + 0x0,
Length: 0 X 4GB + 654336 bytes
Reserved: Base Address: 0x0 X 4GB + 0x9fc00,
Length: 0 X 4GB + 1024 bytes
Reserved: Base Address: 0x0 X 4GB + 0xf0000,
Length: 0 X 4GB + 65536 bytes
Usable RAM: Base Address: 0x0 X 4GB + 0x100000,
Length: 0 X 4GB + 13631488 bytes
Reserved: Base Address: 0x0 X 4GB + 0x7ff0000,
Length: 0 X 4GB + 32768 bytes

Length: 0 X 4GB + 32768 bytes
Reserved: Base Address: 0x0 X 4GB + 0xe00000,
Length: 0 X 4GB + 2097152 bytes
Usable RAM: Base Address: 0x0 X 4GB + 0x1000000,
Length: 0 X 4GB + 117374976 bytes
Reserved: Base Address: 0x0 X 4GB + 0xffff0000,
Length: 0 X 4GB + 65536 bytes
-- cut --
So looks like GRUB detected all available memory anyway. But I'm need memory
in linux, not in GRUB ! And here GRUB fails horrible. With LiLo I get
this :

That is zone(0) is smaller and no zone(1) at all ! What can I do ?
