After patches Solaris won't boot past Grub

I had an unpatched Solaris 10 11/06 system that I finally got around to patching. I selected all 98 available patches and let it do it's thing. Everything went well and I did the required reboot and many of the patches that were applied right before shutdown failed, but quite a few were successful.

The system comes up and once Grub timed out nothing happened. The Grub screen went blank save for the blue background image. All other text and graphics are gone.

What should my next step be? The patching took so long that I left it semi-unattended and I don't know which patches did and didn't install. Whatever happened my system is currently stuffed.

Thanks

I forgot to add in my original post that I can't boot the failsafe either. Like the regular boot, failsafe hangs with only the Grub background on the screen.The filesystem seems to be alright because I can cat /etc/release and it gives me the software version as expected.

Now that I have had some time to read up on Grub/Solaris I enabled the kernel debugger and get the following output:

root (hd0,0,a)

Filesystem type is ufs, partition type 0xbf

kernel -kd /platform/i86pc/multiboot

Error 1: Filename must be either an absolute pathname or blocklist

I'm not sure what to do next. No matter what path I put to the kernel I get the same error.

Well, there is one more thing to change; append the -k or -kd parameter at the end of the kernel entry, after the path... Otherwise, you will always get the path message.

In the end I reinstalled Solaris. There were several things I wanted to do differently and this was my opportunity. All data was easily recovered since I could still mount my filesystems.
