Onderwerp: Re: MSXDOS 2.20
:] There only exists a MSX-Dos KERNEL v2.20, but the MSXDOS2.SYS-program is
:This is not true. The MSX turbo R ST has a KERNEL v2.30 and the GT has a
:KERNEL v2.31.
Oh, I did not know that.
:The main difference between 2.20 and 2.30 is that 2.30 has support for the
:R800. That is, it switches to Z80 mode before calling the low level drive
:access routine and back to R800 mode when done with the low level drive
:access routine. This is needed to prevent timing problems, especially with
:the head repositioning. I do not know the exact difference between 2.30 and
:2.31. I guess that 2.31 has some bug fixes. But not enough as there are
still
:some subtle bugs in the CPU switching routines :-(
But v2.32 has got quite some updates, in example the IF
EXIST-batch-commando. but ofcourse not very major like new commands in the
Bios... Else it would have been called v2.40 or so...
