Dear customers,


I have some user who like to use SD DISK II emulator on their APPLE II plus.

I tried to remove the FDD issue but, there is some tricky timing issue of SD DISK II card.

Hence, I skipped the hang issue for APPLE II plus.

This issue doesn't have on APPLE IIe or IIGS only can see some APPLE II or II plus.

Please use this firmware to able to use FDD.

This patch is deactivate FDD write update to image file then works FDD function.

Just it doesn't update image file evenif wrote the FDD.

Some days ago, I just has original APPLE II plus and can see the issue.

(I had APPLE II plus clone. it doesn't have this issue so, I can't aware where the issue came from.. sorry for this)

Please use this BIOS for APPLE II or II plus only.

Other model users no need to use it.

I will announce if i have better fixed version.


SDBIOS.ROM


Thank you

Dear all,


This is test version not final version.

It took so long time after I mentioned this menu driven boot..

Sorry for late, Just have time to see what SD DISK][ Emulator going to change.


This version of firmware, it starts to support 'Power ON Boot menu'.

You can select image file without Serial dongle nor LCD&Dial controller.


Please read how to use it.

After POWER ON your APPLE II, Simple menu will appear.



You can select a file for boot.

It will load into D1 for booting.


For example, 13 is DOS33SP.NIB file, if you key in the number(HEX type), 

SD Emulator will load the file into Drive-1 for boot. 

If HDD file, it will load to HDD and will boot with HDD Mode.


It doesn't scroll back.. So, you can't see many files.

(I'm working on it)


Commands

Number(HEX) will accept(00 to FF).

If the selection is directory, It will act as Change directory and show files.


0 is go to upper directory.(Cd..)


ESC

Exit this menu and start as before.

If you press EXIT button on the LCD&Dial controller, SD DISK][ Emulator stop to service this menu function.

Will start just as before.


** This menu will start once when APPLE II POWER ON.

If you want it again, Press 'RESET' on Dial controller. then PR#6 will work for you.


Enjoy with this new features.


* This versionis patch of V2.59M.

Bug fixed for 2MG (on HDD mode) support.


SDBiosV2.59N.zip




Anyway, I will enhance this menu program for you.

Thank you
