Yup. Above is compiling all the FCode from the primary bootblocks. 
That's good - it managed to read the initial blocks and get through 
evaluating them. (I fear it's going to mush itself together in the 
email, however. Ah well).

O.k. - the above says it *did* manage to execute the do-boot. Since 
you've given it the -H flag, it should have stopped about four tokens 
in. The only thing it could be executing was "parse-bootargs", and that 
hadn't failed on us before.

Are you sure you're giving the command "boot cdrom -H" (capital H)?
