Ok, were is it done in LB is entering protected mode a standard procedur of LB.

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 Seems that the FPU is always enabled. chris > Stefan > -- linuxbios mailing list [email protected] http://www.openbios.org/mailman/listinfo/linuxbios
