How to run NON-ATAPI Mitsumi CDROM without interrupts ?

Post by hemmerl.. » Thu, 20 Jan 2000 04:00:00

Hello !
I got an old MITSUMI DoubleSPeed CDROM (non-ATAPI = older) with own
16-bit controller,
IRQ 11, IO $340.
I am trying to run Debian Linux of mid 1999 (2 CD edition from the
german CHIP special magazine)

With the Mitsumi kernel module, the usual parameters are
for my controller. But this hardware does not work correctly in
interrupt mode (a timeout occurs when addressing a cdrom for reading
bigger files). So for MSDOS and WIN95, I am using the "poll" mode -
works great for this old computer.

m?? - I dont remember the eact mnemonic as I am typing here, but I know

So how may I configure the Mitsumi kernel module for non-interrupt
operation = poll mode
is the wrong solution

Please answer to the newsgroups AND please answer personally.

1. Support for NSCD-2X-P non-ATAPI CDROM

An old sound-card-interfaced CD-ROM recently came into my possession
(with the sound card). Its model number is NSCD-2X-P, and I think it was
made by Funai. It attaches to a port labelled "Panasonic" on the sound
card, which is afaik made by Prosonic.

The unit works fine under DOS/Wingdoze (ugh) using the drivers supplies
on a floppy. The problem is that I can't get it to run under Linux. From
reading the mini-howto and other docs, it looks like the sbpcd driver
should be the one to use, but it fails to detect the CD-ROM both from
autoprobing and from parameter-passing at LILO.

Is there something I'm missing? Or is it simply that this CD-ROM is not
