Starting a new thread to have a top post here with always-current URLs for the Missing Manual for the U1MB/1088XEL. I'm also creating a ePub doc version of it as well.

 

The most current versions should always be available at these URLs:

 

PDF:

https://www.dropbox....urrent.pdf?dl=0

 

 

ePUB:

https://www.dropbox....rrent.epub?dl=0

 

 

 

Please post any comments, suggestions, corrections or gripes below and I'll add them to the document if they will make it better!

 

This document should help anyone who knows about classic A8 devices but is just getting back into the modern scene and had purchased or aquired a 1088XEL or U1MB and wants to effectively use them.

I'm not sure what specific relevance MrAtari, MYIDE-II or MYBIOS have to the 1088XEL project at all. No offence to either, of course, but MYBIOS is not part of the 1088XEL firmware. One may flash any OS to the U1MB OS slots, of course (MYBIOS included), but to acknowledge them all (Q-Meg, for example, which is supplied in one of the default OS slots) would be a lengthy and pointless exercise. Likewise one may plug in an Ultimate Cart, UNO Cart, etc, all of which are equally useful.

 

The stuff about 32MB partitions still requires correction; as I wrote previously, only the available filesystem imposes any limitation on size (aside from the limitation imposed by 28-bit LBA addressing). So really it would be appropriate to say that most available file systems - owing to 16-bit cluster addressing - are limited to 16MB partitions, while SDX can address 32MB partitions by virtue of the fact that it's the only currently available DOS capable of using 512 byte sectors. Using FATFS.SYS, even that limitation is removed (since clusters may typically be 4KB in size).

 

Likewise the 15 drive limit is really a software limitation. If SpartaDOS X - for example - chose to use more than four bits for the device ID, we could have 26 or 100 or 256 hard disk partitions mounted and addressable simultaneously.

 

The other salient point - which may already have been observed - is that SDX is not a requirement for the use of FDISK, etc. Most of the APT tools may be used with MYDOS, etc, if the user so desires.

You are correct- I'm going to re-organize the manual to have 1088XEL / U1MB sections and then a misc part at the end. I have just been collecting so much information about these add-ons and HD projects that I may have gotten carried away.

 

I realize that the limitations are not due to your FW, I want to keep the Manual on a level that will allow quick reading and understanding without getting too deep into the weeds- I want to direct people back to your more comprehensive manuals for that level of technical explanation.
