Hello Raymond,
What exactly do you mean with 'it does not boot'?
Do you see the MSX logo or the boot text of the IDE?
If not, then your 2048KB memory module is probably not working fine, causing
the MSX to hang.
Grtz,
Jon

see page 123 of the V9938 databook: the difference is in the timing of the VRAM

Hi colourless people,
you could try the following two things:
1. The V9958 requires a *clean* 5V on pin 21 to power the video outputs; If
there is noise on this 5V, then this will result in noise on your video signals
and degrades image quality. On the 5V which is used to power all digital

I didn't follow the whole discussion about the ROM format, but perhaps
it is a good idea to use 'masks' for emulating the 'sensitive' addresses
in ROM/RAM mappers. In most cases, the hardware only checks certain bits
of the address and not all of them. For example, when only the 3

About the bootprocess:
To boot from a partition, the following things must be ok:

performed by the IDEbios at startup. It looks for a valid partitiontable

When pressing DEL, no IDE driveletters are created (and thus preventing
to boot from a not yet good formatted disk),
The patch of COMMAND2.COM is not really necessary. It only makes sure
that the number of kilobytes free is correctly displayed when doing
'DIR'.

You should use MSXDOS2.SYS version 2.2x and COMMAND2.COM version 2.2x
because the DOS2kernel you are using (inside the IDE) is version 2.2x.

What Maarten thinks is correct;
When you save to the ASMformat, also the precompiled code is saved. So
if you load an ASMfile, the compilationprocess goes equally fast as when
you just typed it. :-) Loading and saving ASMfiles goes very fast (is
only a dump of the internal memorybuffers to disk).

Yes, it easily can if you have an IDE version #4.1 interface because
