Chad,

Level1 NitrOS-9 has an mfree result of 137 pages while Deskmate 1 gives 162. 
That should explain the "NOT ENOUGH MEMORY" message.

It seems your main request is to use Deskmate 1 with the disk hardware on your 
system. You have said the disks are assigned Top 0/1 and Bottom 2/3 in your ROM 
but that may not be enough information. That just says what DIR0-DIR3 will 
access not what the values in the ROM drive table actually are. This is 
important as your easiest solution is to modify the CCDISK drive table on the 
Deskmate disk to match your hardware.

On the stock Deskmate disk, the drive table values are at CCDISK bytes $209 
01,02,04,$40. These are the drive masks used to access the four floppies if the 
modules are present in the OS9Boot file. Deskmate has only /d0 and /d1 in the 
bootfile.
You probably need to change the table to match that in your ROM. My guess would 
be your ROM table is 01,$41,02,$42 based on your description. The more usual 
table would be 01,02,$41,$42 making the top drive 0/2 and the bottom 1/3.
Antway it looks like you need to change the CCDISK table to 01,$41,02,$42.

 From the thread I've been reading, that could be more trouble for you than the 
effort is worth. Would you like me to e-mail you a modified disk?
