 If the system loads the kernel, then BTX is not the issue.  The question is 
 what is the install CD intending to load as the root filesystem?  Is it 
 trying to load a memory filesystem and that is failing?  You'd need to 
 examine the messages from the loader itself to see if mfsroot is failing to 
 load.  There have been some reported problems with gunzip of mfsroot's 
 failing because the loader has grown over time and the stack and heap have 
 started growing into each other.  I MFC'd some changes to 6.x and 7.x today 
 that move the heap to prevent this.  Those have fixed the other reported 
 issues, so if this one turns out to be a problem with the mfsroot failing to 
 load then that might explain this issue as well.
