IDE BIOS v2.50 released

After almost 8 years, Jon de Schrijder, the creator of the BIOS for the Sunrice IDE/Compact Flash interfaces released an update for this BIOS. In our forums, people mentioned problems with their IDE/CF interfaces when using FAT16 partitions for a while now, and this has finally been solved. Most notably the update fixes an issue in the DISKIO routine that only occured when using FAT16 and accessing a sector past 65535 in a partition. The updated BIOS can be downloaded from our downloads database.

Infos for blueMSX users :

- rename IDE250.DAT as SUNRISEIDE.ROM and put it in Machines/Shared Roms sub-directory (it will replace the previous version)

- if you use the Ciel Expert 3 IDE machine , keep at the moment the IDE240a.ROM in the sub-directory for this Brazilian machine and wait for an adapted version of IDE250 ( when IDE250a.ROM will be available, a small change will also be required in the config.ini file)

"Bios para interface IDE da Sunrise, patcheada para apresentar as mensagens de erro do DOS2 corretamente nos micros da CIEL. Funciona corretamente em todos os outros micros também."

= "Bios for the Sunrise IDE interface, patched to display DOS2 error messages correctly on CIEL computers. Works correctly on all other computers as well."

Actually, the IDE250A rom is already available Smile

If this is a bug fix, wouldn't it be better to contact Jon about it, so he can take it along in the next revision of the official firmware?

I barely can believe! After all those years! Thank you so much! Big smile

This 2.50 BIOS boots fine with my 2GB CF cart (1 FAT12 + 1 FAT16 partitions), but when I try to boot it using a 2GB SD card connected to a SD to CF adapter, it throws me the weird error "NO ENOUGH MEMORY" and freezes the MSX (FS-A1ST, 512KB RAM).

This 2GB SD card has a single FAT16 partition and boots fine both on my LPE-MMC-V8 and on my OCM. Is that error expected on this new BIOS for the IDE interface? On the previous versions it also didn't booted, but I was guessing that it was because of a bug on that version of the BIOS.

I've both my ATA-IDE+RS232C and CF ATA-IDE , they both work fine since the update ...
If I had a wish to make is that the next version of the BIOS and IDEFDISK allow to have more than four 2GB partition , actually ten would be perfect the could allow me to have all my msx software onto my msx Big smile Big smile Big smile Big smile Big smile

Well, both the LPE-MMC and the MegaSD can boot FAT16 partitions just fine. Smile

Found a bug. Don't know if Jon reads this. He's not responding on e-mail.
Commands FORMAT (for FDD) and RAMDISK don't work in MSXDOS2 (gives "Invalid MSX-DOS call" error)
