since i have 512 mb ram and the onboard gfx chip uses 8MB (can switch to 1MB
in the bios) i decided to try to set the mem to 504 (512 - 8 = 504)
when i use mem=504M as boot parameter, 2.4.3-ac1 boots and all the other
kernels i tested up to 2.4.18 boot with mem=504M.
2.4.19 however doesnt and 2.4.20-pre4 doesnt as well.. no mem=xxxM line helps,
they always hang at "Ok, booting the kernel."
Kernels prior to 2.4.3 didn't need a mem=xxxM line at all.
Here is some info about the system:
Epox 4G4A+, i845G, onboard HPT372, onboard Realteak RTL 8100B, onboard
Integrated Graphics Controller, ... 512 MB Double Sided DDR Ram 2.5 V, P4 2.0
