The perfect sulotion seems to be enabling the L1 cache in the early state of LB.
9s for vga is not fast, but I think we would find the reason for that. if there is any.
Ok, There are a few questions for me exspecially for the cr0 register.
as I say default is 60000010h
for that default the CPU is in real Mode. If I understand that right, it is a 16bit machine ?!
More, in the Config.lb under the motherboard folder is following line in the Setup RAM Section.
mainboardint cpu/x86/fpu/enable_fpu.inc
that file does something on register cr0, but for the GX1 in cr0 is nothing about fpu?!
question:
what do this line
andl $~(1<<2), %eax /* found in enable_fpu.inc */
can anybody explain this in easy words ;) which bits are set in that case.
