Hello to seabios list (and to direct participants of below thread),

I have problem to boot to GRUB from SeaBIOS, since I was able to overcome some of the obstacles on my way to here. Now I am blocked with the KBD: int09h_handler(): unknown scancode read: 0x5c!

I was researching/goggling around, and I was able to determine the main cause why KBD does not work. Here is the update.

I found the thread: http://www.seabios.org/pipermail/seabios/2012-March/003288.html

Unfortunately, the SaeBIOS code has been changed.  In src/usb-ohci.c I could not find any more ohci_free_pipe(), there is only ohci_free_pipes(), so I am not able to apply patch:
diff --git a/src/usb-ohci.c b/src/usb-ohci.c
index 7a437ad..4e020cb 100644

The reason (my best guess) is that from march 2012 to Present SeaBIOS changed significantly.

Another patch which converts alloc_low() to alloc_high() (3 calls) I found and applied, but so far it did not work.

Could anybody advice what I should do to overcome this problem?

Thank you,
