Hi. |
| 2 |
|
| 3 |
Running Gentoo/amd64/hardened with 2.6.17 on an HP DC5100 in EM64T with 4GB |
| 4 |
I've hit a wall on using all the memory, only 3200MB are reported. I've |
| 5 |
googled a lot but couldn't get the missing memory to work. |
| 6 |
|
| 7 |
- the BIOS doesn't do any memory hole remapping, the upgrades available only |
| 8 |
mention cpu microcode support changes |
| 9 |
- the bios doesn't let me disable pci express (some ppl say that's the worst |
| 10 |
mem addr eater) |
| 11 |
- tried the mem=exactmap mem=640@0 mem=... in many combinations, with flat |
| 12 |
and sparse kernel options |
| 13 |
- tried disabling acpi |
| 14 |
- tried with pci=nommconf |
| 15 |
|
| 16 |
Is there anything possible to make the kernel recocnize and reallocate that |
| 17 |
missing memory? Dmesg below. |
| 18 |
|
| 19 |
Thanks! |
