In this case, isapnp configures the card.

Using a modularized kernel, modprobe also loads the driver without any
further parameters:

lunix:/home/schabi/public_html/scsi# /rescue/sbin/isapnp
pnpconfig_nocheck.txt
Board 1 has Identity 08 0f 6d b9 45 42 15 90 04:  ADP1542 Serial No

So the isapnp tools can configure the card correctly.

The further way? (was: Re: AHA-154X/1535 not recognized any more)

[Markus Schaber]

Hello,

[some Test results]

So what's the further way to go?

We found out that the kernel isapnp fails, while the isapnptools (with
"check" entry removed and the driver as a module) and a non-pnp
environment (where the BIOS initialzies it, and either a modularized and
a compiled in driver) work with this card.

Do I (as a non-kernel-hacker, and with only basic C experience) have any
chance to quickly read into the code and find and correct the bug? Or is
there anyone around here who just needs five minutes to adjust a few
lines?

As I said, I don't need the card any more, and am just waiting for this
thing to be resolved, and then I remove this ancient thing. I could even
send it to one of you per snail mail for some weeks to let you do
further tests. My intention was to give a possibility to get the bug
fixed :-)
