One of the many delicacies of LinuxBIOS is that it enters protected mode (32bit mode) after only 17(!) CPU instructions.
Ok, were is it done in LB is entering protected mode a standard procedur of LB.
I.e. the GX1 have to set bit 0 on CR0 to 1
Oh, I have found that stuff :D And I'm confused now.
It seems, I have to write my own entry16.inc code for the gx1. The default entry16.inc should enable the cache for example, but there are written false values to the cr0 register.
in easy words: none. bit 2 is cleared though.
Thanks for the leson ;)
Ok, for the GX1 the EM is set to 0; Emulate Processor Extension, if EM = 1 all flaoting point instructions causes a DNA fault 7
This is done twice for the gx1. First in entry16.inc Later with enable_fpu.inc
Is it posible to remove the line from the Config.lb for the fpu?
