The keyboard doesn't need much setting up - the BIOS defaults are pretty good to my way of thinking. On real hardware, it would be nice to speed up the keyboard's repeat rate to be more responsive; and there's a BIOS function for that. Better call it before leaving Real Mode...
Unfortunately, this code doesn't work well under VMware. To the end I've commented it out.
; ; Boot/Key.inc ; ; Use the BIOS to speed up the keyboard to as fast as it will go Key.SetRate EQU (BIOS.Key.SetRate.Fn << 8) | BIOS.Key.SetRate.Set Key.Rate EQU (BIOS.Key.SetRate.Delay.250 << 8) | BIOS.Key.SetRate.Rate.300 Boot.Key: ; The following doesn't work as intended under VMWare ; MOV AX,Key.SetRate ; MOV BX,Key.Rate ; INT BIOS.Key.Int
