Hi,

find attached the output of superiotool -dV.

The parallel port part:

coreboot:
LDN 0x03 (Parallel port)
idx 30 60 61 62 63 70 74 f0
val 00 03 78 07 78 07 04 03
def 00 03 78 07 78 07 03 03

prop. BIOS:
LDN 0x03 (Parallel port)
idx 30 60 61 62 63 70 74 f0
val 01 03 78 00 00 07 04 08
def 00 03 78 07 78 07 03 03

Any hints are appreciated.

Regards

Andi
