I'm trying to install CentOS SPARC, but the problem comes after i make "ok boot cdrom", the machine starts to boot, but i get the below ouyput
Environment monitoring: Disabled Executing last command: boot cdrom Boot device: /pci@1f,0/pci@1,1/ide@d/cdrom@0,0:f File and args: SILO Version 1.4.9 \ boot: Allocated 8 Megs of memory at 0x40000000 for kernel Uncompressing image... Loaded kernel version 2.6.9 Loading initial ramdisk (2051440 bytes at 0x3F802000 phys, 0x40C00000 virt)... \ Remapping the kernel... Fast Instruction Access MMU Miss ok
After that it doesn't get any further, and i can not continue with the installation. Am i doing somethig wrong? Is it problem with the CD's?
Thanks for the help..

It would appear dodgy boot media can be the cause of MMU Miss errors. Have you run md5sum against the CD and compared that to the original ISO?
Will.

Yes, i already run md5sum and it worked, the only thing i think is that may be a problem with the cd's.
I downloaded the bin-cd's from http://beta.centos.org/centos/4.2beta/isos/sparc/
Where can i find another repository to get the CentOS SPARC cd's?

What speed did you burn them at sparcs sometimes baulk at media written at fast speeds burning at 4x should work fine

Or a dirty or erratic CD drive in the sparc. Try to write the images at a very slow speed, no more than 4x, and see if that helps.

Can you try switching off auto-boot, then trying again- I think I remember seeing this on a netra T1 I was playing with a few months back. So do something like:
ok setenv auto-boot? false ok #. lom> poweroff lom> poweron ok boot cdrom
I did get on netra T1 working ok, however another one had its clock running about twice as fast as it ought to! Neither went live for any useful purpose, it was just an experiment.

The original problem you had ("Fast Instruction Access MMU Miss") is some strange thing that happens if you had Solaris kernel running on the machine after last power-cycle. Just turn the machine off and then on to solve it. I've seen that on all Sparc boxes I had access to (mostly Ultra 1 and some Netra boxes).
For the second problem (after you power cycled machine), it's kinda strange. Can you check that your cdrom is really on /pci@1f,0/pci@1,1/ide@d/cdrom@0,0? The above message could also happen if media was not in the drive (if working remotely, have somebody check if CD got ejected or something) or if the media is corrupted (try burning another CD).
The setting of auto-boot variable shouldn't have any impact on either problem you were experiencing (the only thing auto-boot controlls is if after poweron you'd go to "ok" prompt, or the machine will start to boot -- it's usefull mostly during installing or troubleshooting so you don't need to babysit machine and race to send break before it starts to boot).
