I don't know what you're smoking, but there is no "probe_keyboard.c"
involved in this. The keyboard probe code is in boot2.c, and it looks
like this:
313 if (opts & 1 << RBX_PROBEKBD) {
314 i = *(uint8_t *)PTOV(0x496) & 0x10;
315 printf("Keyboard: %s\n", i ? "yes" : "no");
316 if (!i)
317 opts |= 1 << RBX_DUAL | 1 << RBX_SERIAL;
318 opts &= ~(1 << RBX_PROBEKBD);
319 }
There aren't any timing parameters there either. Either bit 4 in the
byte at 0x400:96 is set, or it's not.
