Hi all,

this patch fixes bug in pnpbios_rawdata_2_pci_dev() - miscalculated length =
of
ioport range. This function uses word at offset 6 in I/O Port Descriptor,=
=20
but according to ISA PnP specification ioport range length is a byte at off=
set 7
and byte 6 is base alignment.

BTW will it usefull to implement PnP device naming function ?

Best regards.
