For those people running OpenBSD on sparc here is the solution I found to
the filesystem type 0 problem caused by a previous RedHat Linux install:
Go to the PROM prompt and:
set-default boot-device (default is: disk net)
set-default use-nvramrc? (default is: false)
set-default nvramrc (default is: <blank>)
Apparently, after a month of looking through all the man pages, mailing list
archives, and FAQs, I finally decided to check through the PROM variables.
Here is what the RedHat install did to the above variables:
boot-device = linux
use-nvramrc? = true
nvramrc = devalias linux /iommu/sbus/espdma/esp/sd_(_at_)_3,0:c
>From the UIUC bsd newsgroup I was told to try clearing the disklabel before
doing an install:
dd if=/dev/zero of=/dev/rsd0c bs=512 count=1
but this did not work in my situation.
Note that this worked for me on a SPARCbook 3GS... Hope this might help
someone out in the future.
