[Coco] "Ultimate" CoCoSDC Image

[Barry Nelson]

Ooops! I sent a rom with the offset set to zero. Check the following bytes:
PRINT PEEK(&HD938):PRINT PEEK(&HD939):PRINT PEEK(&HD93A)
That should return
5
160
0
Unfortunately, I just checked the copy I uploaded and it will return
0
0
0
instead. Try this after starting HDBDOS:
POKE &HD938,5:POKE &HD939,160:POKE &HD93A,0:POKE 113,0:DLOAD

If that works, reflash the HDBDOS, but insert these pokes in line 125 of the FLASH.BAS program before you run it. This is ONLY for this HDBDOS image. If you use it to flash other ROM's do not add these pokes.
125 POKE &H5938,5:POKE &H5939,160:POKE &H593A,0

This will set the offset to where the BASIC disk images start on the hard drive.
