U1timate 1MB/Incognito/1088XEL Firmware ======================================= Copyright (c) 2015-2019 Jonathan Halliday Please read LICENSE for licensing details. Visit atari8.co.uk/firmware/ for updates. CONTENTS ======== In the archive you will find stand-alone files, and those same files on ATR disk images. Files (U1MB/1088XEL): FIRMWARE.ROM ULTIMATE.ROM ULTNOGOS.ROM SDXUL192.ROM SDXUL256.ROM SDXUL320.ROM LICENSE Loader changelog Main BIOS changelog PBI BIOS changelog readme UFLASH.XEX Files (Incognito): IBIOS.ROM ILOADER.ROM IPBI.ROM INCOG.ROM INNOGOS.ROM SDXIN192.ROM SDXIN256.ROM SDXIN320.ROM LICENSE Loader changelog Main BIOS changelog PBI BIOS changelog readme UFLASH.XEX FIRMWARE.ROM is a 64KB firmware image which you should flash to the 'Firmware' slot using UFLASH if you just want to update the firmware on its own and leave SDX, operating systems, etc, intact. Since the Incognito firmware cannot yet be bundled into a single file, it is supplied as three separate files: IBIOS.ROM, ILOADER.ROM and IPBI.ROM. These files should be flashed to the 'Main BIOS', 'Loader', and 'PBI BIOS' slots in the listed order. ULTIMATE/ULTNOGOS.ROM and INCOG/INNOGOS.ROM are complete flash images with a selection of operating systems, BASIC ROMs, and either a 192KB version of SpartaDOS X and a demo of the WIP Graphical OS, or a 320KB version of SDX and no Graphical OS. Unless one is interested in testing the Graphical OS, the complete ROM with the 320KB SDX build is probably the most useful, since it preserves a complete set of MAN files on the CAR: device. The rest of the ROMs (whose names begin 'SDX') are SpartaDOS X ROMs which include the APT FDISK partition editor and the LSDEV and LSDSK tools pre-installed on the CAR: volume. These same SDX ROMs are present in the 'complete' 512KB flash ROM images. INTELLECTUAL PROPERTY ===================== Note that while the this firmware is closed-source freeware (as described in LICENSE), it includes a modified version of the GPL licensed High-Speed SIO driver by Matthias Reichl. Special permission was sought and granted to incorporate Matthias' code into this closed-source project. Matthias deserves creadit and recognition for his remarkable work in the area of high-speed SIO on the 8-bit Atari, and the 'alt' U1MB firmware is richer for the inclusion of his driver. Aside from the aforementioned high-speed SIO driver and the customised SpartaDOS X ROMs included in the archive, all components are the wholly original work of the author and consititute a 'ground-up' rewrite of the original firmware. See the user manual and developers' technical documentation for further details. ACKNOWLEDGEMENTS ================ As well as the aforementioned Hias, thanks to Micheal St Pierre, Marlin Bates, and everyone in the 1088XEL beta testers discussion. Thanks to Avery Lee, Marius Diepenhorst, Lotharek, Candle O'Sin, TheMontezuma, and many others for your vital contributions and support. DONATIONS ========= Since the amount of time required to develop and maintain this firmware is considerable (and at times unmanageable), donations are most welcome and may be made via www.paypal.me/flashjazzcat. FEEDBACK ======== The author welcomes feedback, suggestions and bug reports. Enjoy! FJC July 2019
