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? chris -- linuxbios mailing list [email protected] http://www.openbios.org/mailman/listinfo/linuxbios
