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.
