32MB ATR?

Recommended Posts

Is there a utility which allows the creation of 512 byte sector ATR files? I want to try and create a 32MB disk image to use with SpartaDOS X. Everything I've tried is limited to 256 byte sectors. I'd use a virtual hard disk (H:) but I'm unclear as to how you're meant to reference such a disk ID from the SpartaDOS command line (surely H: is translated to D8:?).

Spartadosx 512 byte sectors not sure how it translates down but as I understand it yes 32.

Up to 15 drives DA: thru DO:

Can somebody update Black Box Prom to allow 15 slots please... I dislike having to have two different partition lists to load.

 

Isn't there a 16mb size limit that the Atari recognizes??

I believe you will need a device that actually has 512 sectors, and I'd be suprised if the H: device in Atari800(Win+) emulates 512 byte sectors. The H: device is more of a way to access your PC files though, so maybe the disk drive emulation is where you would look for 512 byte 32MB ATR support.

It looks like sector size of the ATR format is either $80 or $100, but since it's two bytes anyway, $200 should work. Whether current tools (like APE and the emulators) will support that is another story.

Thanks. I understand that the H: device would offer potentially unlimited storage and is entitrely separate from the 512 byte sector issue... I probably didn't word the question too well in that respect. I meant to point out that I want to try and create a 32MB ATR image under emulation. Clearly the way to do this is with 65535 sectors at 512 bytes per sector, and I wanted to experiment with the 512 byte sector buffers in the latest version of SpartaDOS. It never occured to me that Atari800Win and variants thereof might themselves have a sector size limitation, even if such an ATR image could be created by another utility. :(

 

This brings me back to another part of my original query: Since the H: device is indeed an easier way to create large storage devices under emulation, is there a way to address hard disks H1:, H2: etc using SpartaDOS X? It seems to me there is no obvious way to reference this drive ID from the SpartaDOS X command processor.

This program:

 

http://drac030.krap.pl/sio2bsd.tar.gz

 

can create and handle 32 MB ATR images. You have to configure and compile it yourself, though (it is written for FreeBSD). Then you can use them from real Atari by means of SIO2PC or something like that.

 

Accessing "H:" (or any CIO device) directly from the SDX command processor is not currently possible. Some device driver is planned to address this issue, but, since supporting emulators is rather far on our priority list (if it is there at all), it has not been yet written.

Have you tried the Emulator Atari800 version 2.03 build from SourceForge, also supports the new SDXversion 4.41 cart.

 

http://sourceforge.net/projects/atari800

 

Yeah, I've tried that one under windows and it works well with SDX 4.41. Most of the time, though, I run SDX 4.41 under Atari800MacX. I find it more or less perfect, apart from some slightly quirky keyboard assignments.

Thanks for the info! I'll give that utility a try and let you know how I get on. It would be useful, especially since the H: device is a bit of a dead-end for me at the moment. ;)
