I am trying to make Panasonic KXL-783A 8X CDROM work on a laptop running
FreeBSD 2.2 with PAO. Following configuration were tried:
1. First I tried to use the PCMCIA card which comes with the drive.
It doesn't have much written on it ("8X CDROM Interface Card.
Panasonic."), but PAO appears to identify it as a FutureDomain
SCSI card. The card's ID string is "KME KXLC003". Nevertheless,
the driver hardware test fails on this card, when the driver reads
0xFF from its status port. Yes, I did go into kernel, put the
debugging statements, etc. etc. - that is how I found it. The driver
is ncv0. It probably means that the status register is on a different
address or the card is based on entirely different hardware. Dunno.
If anybody has any ideas on how to modify it to accept
the card, feel free to let me know. I'm not an expert on kernels and
drivers though, so you may want to stupidify your explanaitons a
little :)
2. After failing with the Panasonic card, I plugged CDROM into Adaptec
APA-1460. When the card is inserted, driver starts scanning the bus
for SCSI devices but doesn't see the CDROM at all. Nothing happens,
just like if CDROM were disconnected from the bus. The same card+CDROM
work flawlessly under Windoze95 though :(.
I would try to use "scsi" command to try poking into the matters,
but it requries at least one SCSI device to be properly configured,
and with only non-working CDROM connected to the bus I do not have
any.
To Tatsumi: If you have any ideas on the subject, please, let me know...
If you want, I can also try screwing with the drivers to make
Panasonic and the infamous 3c562 cards work, but being a
newbie in these matters I will probably require your help.
