Hi.
I created experimental patch for TI-12xx PCIC, this patch was
originally from PAO3 sys/pci/pcic_p.{c,h}.
Some NOTE-PC and it's BIOS did not initialize TI-12xx PCIC. If it
was not, we can't play PC-Card in 4-current and 3-stable on that
NOTE-PC.
Sorry, currently I only imported PAO3 code, and fixed some
differences from PAO3 and 4-current to compile it w/o error.
I think it has some problems, but it is useful for NOTE-PC which
has poor BIOS....
Current known problem in my NOTE-PC, NOTE-PC does not recognize
card insertion/removal after boot. So I use pccardc power comment
like this:
at insertion:
STEP 1.
(insert PC-Card slot 1)
STEP 2.
# pccardc power 1 1 (power-on Slot1)
at removal:
STEP 1.
# pccardc power 1 0 (power-off and virtual removal)
STEP 2.
(remove PC-Card from slot 1)
P.S.
this patch is for 4-current.
Comments are welcome.
Thank you
