You can ask me for details. The design is quite old and not supported any more but i can find bits here and there. A newer signle-chip solution exists, by the way.

Hi msxegor

I've already build the BEER IDE that is fantastic on MSX1 Big smile
Now I'd like something more powerfull with DOS2.

Do I need HDPREP or I can use BEERIDE.EXE ?
I've compiled the ROM but it's only 16ko. Seem to miss DOS2 inside.

Interested in the single chip solution Wink

Thanks for your answer

Actually, i have the single existing prototype, but when i got that, it was rom-less Sad
The only problem with beer it's slow. It does work with DOS2 in another slot.

Don't understand how it can works without rom.
The single chip manage 1Mbit rom.

Can you answer me what do you use to format disk.

I've never succeed in BEER+DOS2

Sorry if I mislead you.
Now, i details.
1. 'Original' Novatec IDE exists only as a single prototype, no ROM installed on board (lost somewhere probably 10 years ago). Of course it doesn't work.
2. 'Single chip version' actually has 2 chips - 128K flash and Altera 7064 to host everything else. Design supports also 128K of RAM for buffers but supporting code was never written.
3. As of version 1.9 which supports FAT16 and large partitions, there is hprep for MSX. No idea what EXE file does, that's not mine program.
4. No idea what's the reason. Worked for me with either original DOS2 cartridge or patched DOS2 in a separate memory mapper. Maybe slot order of beeride/dos2 is critical.
