Read this firstDue to differences in card manufacturers the advisable card-size should not exceed 4Gb.*Cards larger then 4Gb can be used, but could need a manual setup in the Init-routine.*
*If CHS-values read: 16383/16/63 you need to do a manual Init.*
The internal basic-bug:The MyBIOS -05 and -06 have issues with activating the internal basic, the OPTION-key does not work as it should (to enable basic).
To enable internal basic do this.
-Normal-mode:
Hold SELECT at boot-up and then toggle Basic ON with "B"
-Image-mode:
Select your image, hold OPTION and press enter.
The screen will garbage-up (indication that Basic is enabled).
Use SHIFT+CONTROL+TAB then "C" to correctly restart the selected image.
The copy image to SIO-bug:The MyBIOS -05 and -06 can not copy images from Image-space to SIO.

The MyBIOS is a completely rewritten Atari-OS that complies to all official released 400/800 XL/XE documentation.Except for relocate-able-drivers and cassette related routines (No room for it, sorry).
The new BIOS is coded to be seen as stock REV_02 (XL/XE) and also patched for OS_B (400/800) programs.
MyBIOS is designed to be downwards compatible.
If you have a program that does not run on this BIOS, please zip and send me a copy for evaluation purpose.
What is MyIDE?MyIDE-II is a interface to connect a CF-card (IDE-device) to the Atari parallel bus-system. Due to the parallel data-transfer it’s extremely fast, at least 10 times faster then standard SIO. In special applications it can reach data-transfers up to 100 Kbytes/second or 200 sectors/second.
3rd Party software.In the today’s world users upload there MyIDE-device with command-line driven “myidetool” and the windows-overlay “MyIDE Drive Manager LBA2”. These two fabulous 3rd party programs are downloaded together with this update. All 3rd party software is included.
FAT32 and ATARIMAX fat32-loader.The BIOS supports FAT32 entry in the MBR on your media for PC-usage.
On this FAT32-area you can copy .XEX .ROM and .ATR files, which you can load with the ATARIMAX FAT32-loader.
APT and SDX.The BIOS supports APT entry in the MBR, to support SDX IDE-driver called “MyIDE.SYS” or “MyIDE2.SYS” made by FJC.
You need to customize the SDX-rom to make it work with MyBIOS and/or APT
The SDX.ROM can simply be loaded with the ATARIMAX FAT32-loader.
Please consult the SDX homepage for manual and SDX-customizer.
MyDOS.With this download you also find MyDOS. This is a popular DOS version used on the Atari platform.
Direct IDE-access.Device X: is a powerful tool to direct access any LBA-sector on the CF.
SRAMDISK.MyBIOS has a standard D8: RAMDISK mapped to the internal SRAM
The driver will reply to a percom command how many space is present depending on ROM-images loaded.
With no ROM-loaded, size is almost 512k.
With SDX 256k version, size is almost 256k.
RESETWith F2, you should NEVER hit RESET.
Use SHIFT+CONTROL+ESC for a reset.

viewtopic.php?p=7445#p7445BUG-report:>Internal BASIC does not switch on with OPTION.
You need to use the SELECT-key during booting then B to enable BASIC.
