Hi, I made the following changes to syscons.c: gotack: DELAY(10); j = 1000; /* Wait at most 10 ms (supposedly). */ while ((inb(KB_STAT) & KB_BUF_FULL) == 0 && --j > 0) DELAY(10); DELAY(10); val = inb(KB_DATA); if (val == KB_ACK && --i > 0) goto gotack; printf("scprobe: Keyboard reset sent %d times\n", 1000-i); if (val != KB_RESET_DONE) printf("scprobe: keyboard RESET failed (result = 0x%02x)\n", val); } ie, I stepped the number of retries to 1000, the following was the result: putte:~> dmesg | grep sc scprobe: Keyboard reset sent 13 times sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA color <16 virtual consoles, flags=0x0> The keyboard works now.
