Re: DEC PWS500au (MiataGL) EIDE Issues

Sorry for the delay!

So, I booted the no-cypide kernel, and it cleared the "stray isa irq" messages. However, I don't seem to be able to do anything with the CD-ROM (stock Toshiba XM-6302b) attached as the secondary slave device.

Here are the boot logs:

<snip>

And, of course, the drive isn't available:

-bash-5.1$ sudo fdisk sd0
fdisk: cannot opendisk /dev/rsd0: Device not configured

Any suggestions?

Thanks!

Hey Alex, sorry I wasn’t able to work on this for a couple of days.

So, I think the first experiment to try is: build a kernel without “cypide” … just use the fall-back “pciide” driver that will only do PIO, and see if that does any better.

I built one for you:

http://www.netbsd.org/~thorpej/netbsd-alpha-9-2-GENERIC-no-cypide.gz

Give that a whirl… if it results in a working drive (using the slower PIO modes), then that narrows down where we need to look.

Thanks!
