[comp.sys.atari.st] ST problems

bw0i+@andrew.cmu.edu (Bryan Wu) (01/19/89)

My friend just got a new 1040 ST and asked me to ask the net about 2 problems:

1. How do you format a disk in double density?  Using the format program on the
DOS disk he has only formats the disk w/ 40 tracks (double sided) but is only in
single density.  This is strange because the programs he bought are in double
density.

2.  Some games that worked on his friends' ST's (a 520 and a 1040, both not new)
but do not work on his 1040.  Some games that do this are: Typhoon and Super
Sprint.  Should he send the ST back to the dealer for repairs or is there a
simple explanation for this?

Any help is greatly appreciated.

All ST formatting programs, and the formatting routine available from the
desktop should format at 80 tracks (optionally, sometimes more).  The only
available option is Single Sided or Double Sided...  is your friend sure
that his disks are really being formatted at only 40 tracks?
 
And just to be sure, is he talking about regular 3 1/2 inch Atari format
disks, or IBM PC style disks?

The answer here is likely to be that his new 1040 has what are called the
"Mega ROMs" in it.  Some software, notably games, violate certain
restrictions and thus won't work with the upgraded ROMs.  This is not a
defect in the machine, but is the fault of the software.  He should contact
the software publisher about an upgrade to the software that follows the
rules..!
 
One possible solution, although not guaranteed to work, is for him to try
loading the old TOS in RAM from disk, if he can find a copy of it.  This
should allow the software to work, but it eats up nearly a quarter of the
memory in the machine.
