Bug#589748: memtest86+: uses e801 memory map instead of e820 memory map under 440BX with multiboot

[Arthur Marsh]

Package: memtest86+
Version: 4.10-1
Severity: normal


When using multiboot option under GRUB 1.98-20100710-1 with following patch
applied, memtest86+ runs rather than reboots on my 440BX chipset machine,
but it uses the e801 memory map instead of the e820 memory map and doesn't 
see most of the RAM. If I get memtest86+ to detect the RAM it finds 383 
MiB of RAM (there is 384 MiB installed in this pc).
