Could you tell if windows have disabled dma
automatically ?
Once you know the "ide controller" your cdrom is bound
to (see the note at the end of the mail):
- open Device Manager > IDE ATA/ATAPI Controller,
select the wanted controller.
- open its "properties" window and switch to "advanced
settings" tab.
There you have two "device data" group (0 and 1). I do
not know how to find which one related to the cdrom
(here I only have the cdrom on the "secondary ide
channel" so it is the entry with a "current transfer
mode").
please gives us the "current transfert mode". I have
"ultra DMA mode 2" here (only as reference, the bug
does not show up on this box). This means DMA is
enabled.
Greetings.

PS: you could try latest >= 2.6.14-rc3* kernels if
your are easy with compiling a the kernel.
The reimplementation of the "IDE" code is mostly
complete nows (this is/was the biggest remaining "not
so good" code in linux).
I do not have access to the box I own which have the
"broken" cdwriter before monthes.
I highly expect your results (even if only the windows
behaviour - disabling the dma or relying on via to
provide a driver with an unknown trick to work well
even with the hardware behaving badly).

"HOWTO find the IDE Controller the cdrom is bound"
... to without opening the box and knowing about pc
internals.
- linux : if your cdrom is on the first ide connector
it is bound tohda or hdb
- windows :
Device Manager > IDE ATA/ATAPI Controller
the open "properties" window for each IDE controller
and switch to "details" tab. In the list choose "Bus
relations" and you will see a name.
This name is in "device manager" cdrom list.
