(the above gave a command prompt

Ok, so it's not that straghtforward. Sigh. There's various hacky
workarounds we could do here, but Windows doesn't seem to do them so I
lean towards suspecting that there's something wrong with our keyboard
controller reboot mechanism. I'll try doing some more tracing.



I'll keep looking around as well(the best I can)

FWIW not sure if this means anything but


grep PS *.dsl

gives:


SPST, 1,
PSVT, 8,
PSCL, 8,
APPS, 1,
PSI0, 8,
PSI1, 8,
If (PSI0)
Store (0x00, PSI0)
Return (CRS (PSI0))
Return (CRSI (PSI0))
Store (SRS (Arg0), PSI0)
Store (SRSI (Arg0), PSI0)
If (PSI1)
Store (0x00, PSI1)
Return (CRS (PSI1))
Return (CRSI (PSI1))
Store (SRS (Arg0), PSI1)
Store (SRSI (Arg0), PSI1)

Method (_PS0, 0, Serialized)

there's no such thing as a PS/3 is there?
