My BIOSes (all AMI) will not emulate an USB-mouse without setting up a far-pointer by 15C207 to a (dummy RETF anyway) routine followed by a 15C200BH01 (enable). Perhaps because my keybords are still PS/2. After this I can use PM/RM port60 mouse routines and ignore BIOS. >> INT13_41 flags, (check if 64-bit address supported) > Is this just an EDD 3.0 check? Yes, is AH=030? but I check if bit3 of CX is set in addition. __ wolfgang
