[Coco] error 249

[Bill]

Do I change the DNS or not?

Here is the ENTIRE list as it comes from a FRESH boot:

DMODE /D0 
nam=D0 mgr=RBF ddr=rb1773
hpn=07 hpa=FF40 drv=00 stp=03 typ=21 dns=01 cyl=50 sid=02
vfy=01 sct=0012 t0s=0012 ilv=03 sas=08 wpc= ofs= rwc=

That is it. The same setup is also set up for /d1. I am using 3 1/2" 80tk drives

I did "ident -m rb1773", and our numbers match.
I did "ident -m rbf", and again, our numbers match.

This just leaves cleaning the heads on the drives.

Thanks
