Messing around with OS9 Level 1 Version 2. Replaced CCDisk and
associated floppy descriptors with rb1773, DD, D0 & D1 from NOS9 Level
1. All this on a 35 track single sided disk. Boots great. Format a 80
track double sided floppy, cobble it, DED OS9Boot so the DD, D0 and D1
descriptors have the correct cylinder count (&H50) and sides (2). Try to
boot it. No dice. Tried with 40 track double sided. No dice. 80 track
single sided. Nothing. Tried every combination. Nothing. Tried OS9Gen
instead of Cobbler. Nothing. I can boot with the 35TSS disk with 80TDS
descriptors no problem, CHD & CHX to a big disk and all works fine. Just
can't make a big bootdisk. I can make all the 35TSS bootdisks I want
using RS-DOS BACKUP. But that's not the point. What am I doing wrong?
Thanks. /Chester
