Flyguille has published the MNBIOS programmer's manual written in English. It consists of 8 pages right now, but Flyguille will translate some pages everyday.

Also on the official MNBIOS website a simple electronic diagram of the hardware MSX4 according to Flyguille can be seen. So that the experts can develop and manufacture this hardware. Besides this you can also read about the latest developments and find out about the official publication of the kernel and user interface.

We're learning more and more about this interesting BIOS Smile
MNBIOS really contains a lot of functions, but a bit too many for my taste... On one side, having a BIOS with all those functions is convenient (especially for less advanced programmers), but one might consider some functions superfluous. It's a matter of taste, really Smile

Flyguille, Thank you for making more and more information available in english, and thank you for creating this MNBIOS! I'm sure a lot of people will benefit from this.

some functions superfluous ----> is because a aplication can't use IN / OUT commands, can't address to the hardware because the norm msx4 forbidden this, because that by example the MNBIOS has a function for read the VDP status register.

is forbidden because a future MNBIOS can support v9990 direct with full compatibility of all aplications writen for v9938 or v9958.

Only a driver program can use IN / OUT commands for address the hardware.

Yes, the MNBIOS has a lot much functions more of 350 to 450 for start, plus the external drivers functions !!!

a external driver can be for example a kernel for video games.

Aha, true hardware virtualisation, nice Smile (But also a bit slow for a 3.58MHz Z80 system ^^Wink

Well, the current speed of mnbios is nice, but not is magic.

The windows or screen scroolling are slow, because is a v9938, you know....

Then you develop for this O.S. you love !!! Is so easy!!!!!!!!!.....

CALL .... CALL .... and more CALL .... DRIVER .... DRIVER .... JP .... and more JP....

DRIVER is a RST masked command!.
