[Coco] Re: [Color Computer] setting up Nitros9 device descriptor for SCSI drive

[Mark Marlette]

Jim,

I let Boisy reply to this since it is a software configuration issue.

Error 246 to me jumps out at me as you don't have the drive id to the 
desired descriptor setup properly.

Has nothing to do with HDB-DOS, that is later after you have the proper 
drive selected. DNS field IIRC...

In general, NitrOS-9 works from the bottom of the drive and HDB-DOS 
works from the top of the drive down. So in HDB-DOS you place an LSN 
sector offset to the first drive, ie drive 0. NitrOS-9 only has to have 
an entry only if you are using multiple NitrOS-9 partitions. The 
Wizard.bas program will do this configuration for you **if** you enter 
the correct data. Also you MUST, in the descriptor tell SuperDriver not 
to autosense the drive size, this will step on your HDB-DOS partition.

SuperDriver is very neat. If you didn't have a HDB-DOS partition you 
wouldn't even have to tell it the cyls, sid, sec, etc...it is all done 
for you.

Some utilities did not take into account the cluster size and assumed a 
size of 1. Run that utilitity that writes to the drive without a 
cluster size of 1 and BOOM, corrupt drive......... :(

The B&B utilites are REALLY bad about this. Ezgen, etc....

I don't recommend a NitrOS-9 partition >127MB because of this. 127MB is 
HUGE!!!!!
