Ok, the lights just came on I think, and this needs to be done to the /sh@ 
dd.bt?

And that figure would be the value of the 3 bytes of sh
{t2|07}/DD/NITROS9/3.2.9/BOOTLISTS:dmode /sh    

 nam=SH mgr=RBF ddr=rbsuper
 hpn=07 hpa=FF74 drv=00 stp=80 typ=81 dns=08 cyl=0023 sid=01
 vfy=01 sct=0012 t0s=0012 ilv=00 sas=08 wpc=1D ofs=BB90 rwc=

called wpc and ofs, plus the offset to the os9boot file, which in this case 
is an additional $0B for a total offset of $1DBB9B, right?

Back with a yay/nay in a bit.
