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.

Rgds/mark
