| |
Hi all, I've got an internal development board based on the Intel 815 chipset and the Intel ACSFL mini-BIOS for embedded systems, and then using grub 0.93 to boot Linux.
under 2.4 my memory is correctly sized at 256MB, but under 2.6 I'm only seeing 64MB,
2.6 gives: BIOS-provided physical RAM map: BIOS-88: 0000000000000000 - 000000000009f000 (usable) BIOS-88: 0000000000100000 - 00000000040ffc00 (usable) 64MB LOWMEM available
2.4 gives: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 00000000000a0000 (usable) BIOS-e820: 00000000000e0000 - 0000000000100000 type 5 BIOS-e820: 0000000000100000 - 000000000ff00000 (usable) BIOS-e820: 000000000ff00000 - 0000000010000000 (reserved) BIOS-e820: 00000000fec00000 - 00000000fec00400 type 6 BIOS-e820: 00000000fee00000 - 00000000fee00400 type 7 BIOS-e820: 00000000fff00000 - 0000000100000000 type 5
So is this 2.6 just being more fussy about the contents of the e820 that my "BIOS" is supplying and falling back to the old style detection?
Dave.
