You could consider doing a netboot (if that works) and doing the install that way. If you weren't wanting to change the disk about then I would suggest copying all the install sets into a convenient location on the machine, copying the kernel to / with a different name. Then try a single user mode boot from the new kernel. If that boots then you should just be able to unpack the install sets using tar (tar zxpf ... ) with / as your current working directory. Have you considered putting a second disk into the machine? You could partition it, unpack the sets, install the new kernel, install the boot blocks (using installboot being VERY VERY careful you get the correct disk). Then remove the old hard disk and (hopefully) boot from the new one. -- Brett Lymn
