Quickly had a look in the KERNEL31 source. The LDOPEN.ASM file contains calls to a routine called MyOemToAnsi, which does the character set conversion. In turn, that function either calls the actual conversion routine in the keyboard driver, or does nothing if there's no keyboard driver yet (boot phase). Didn't find the keyboard driver part, probably not part of the actual kernel so it makes sense that it's not there. Anyone knows where to find one?
