32-16-32 transition in vgabios.c and 16-32-16 transition in idt.c. The problem is that 16-bit code segment descriptor (0x28) has base address zero and 64K limit. (I studied these code to implement my own 32-bit legacy services but abandoned it because vm86 starts looking inevitable...) Perhaps we can put these functions in a special section and modify the ld script to put this section near the beginning of image so that these functions will be located below 64K for most cases. > Do you think you could test a new vgabios.c for me? Sure. My EPIA doesn't need the fix but I can confirm the fix doesn't break it. -- Takeshi _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
