File: src/sys/boot/i386/boot2/boot1.s The code to enable A20 gate will hang on "legacy free" systems without a keyboard controller at port 60 / 64. Suggest adding some sort of time-out to proceed anyway if expected reply does not come within a reasonable time. Or bail immediately if FF is read. Thanks !
