공지사항

SDBIOS.ROM


Dear customer,


I'm glad to announce new firmware V2.51

From this version, It supports some copy protected NIB image and you can run it on your real APPLE][ and fixed several bugs.

I don't have enough to test protected image so if you have but not working with Emulator, please send it to me for more test.

Please update your SD DISK][ Emulator and enjoy it.




What was changed?


1. Reading routine was improved and run some of non standard DOS33 NIB image DISKs.

2. DSK file booting fault bug fixed.

3. Above than 70 DSK file selection bug fixed.

3. Above than 70 Directory selection bug fixed.

4. No terminal command allowed while running SAVE and DISK updates. (may have error if key in happend)

5. On the terminal, '1' is going upper directory it is the same command as 'CD..'

6. Writing/Updating status marks was changed for better view on Teraterm.



How to update firmware

 

WARNING

! Your APPLE][ must not lose electric power or be powered down while the firmware 

is updating.  If this happens, the SD Disk][ may to fail restart, or you won't be able to update firmware anymore.

In this case, please return the board to me for re-programming. (Free of charge to fix this issue but all shipping costs will be your responsibility).

If you are ready to upgrade, please read first and follow below carefully

 

1) Power OFF the APPLE][ and open the cover of your APPLE][.

2) Remove the SD Memory card only, leaving the Disk][ board in the computer. (Present working SD Memory card should work fine)

3) Copy the firmware(SDBIOS.ROM) to ROOT directory of SD Memory card and insert it SD card slot on Emulator board.

4) Push Dial button (YES) +Exit button simultaneously, then power ON the APPLE][.

5) Then release a while later. You will see as 'system check..................................'(if set 115200baud) on the terminal screen.

6) A while later, SD DISK][ Emulator will restart.

7) Once the SD DISK][ restarts, re-programming of the SD Disk][ card is complete.  Re-start your computer to enjoy your updated SD Disk][



Thank you

Ian Kim
