Re: [SeaBIOS] [coreboot] Seabios problems

I am back.
I give you those logs:
- I still have keyboard troubles in debuglevel=4
- Vista doesn't boot with your patch.

Thanks for your help.

Thanks.  Can you try the following for the keyboard problem?

--- a/src/ps2port.c
+++ b/src/ps2port.c
@@ -306,6 +306,7 @@ aux_command(int command, u8 *param)
 static void
 process_ps2irq(void)
 {
+    return;
     u8 status = inb(PORT_PS2_STATUS);
     if (!(status & I8042_STR_OBF)) {
         dprintf(1, "ps2 irq but no data.\n");

Your keyboard definitely wont work after this, but I'd like to see if
the init succeeds with it.  (I think there may be a case where
interrupts are messing with the initialization.)
