eh.. I am. But for the moment I have to 'freeze' my msx-activities (except
this mailinglist :-) ) till February due to a lack of time; tests at
university :-(

It depends... I'm still busy making an ATAPI driver (built into the rom)
that works for all ATAPI-devices. There are two problems:
*most (cheap) ATAPI devices (CDROM...) don't comply with the ATAPI
standards what timing concerns; which makes it difficult to make a driver
for all MSX's and most common CDROMs
*all documents I've found on the net describes the protocol when one uses
an interrupt facility. The MSX IDE doesn't make use of this hardware
interruptline on the IDE bus. Nevertheless the documents say it is
possible to use only polling whithout the need to use interruptstuff.

no; (I have a tech. manual about the LS120 though)
Let's first make a good ATAPI driver.
Note: the current CDROM utilities delivered with the IDE do only work
with some types of CDROMs due to all different timing schedules around.
