what is the win 98 /95 equvalent of nt4 cdaudio.sys filter?

1

Hi all,
Under win NT cdaudio.sys is a filter driver, which allows the playing of
audio CD via standard commands, which are then interpreted by the filter
into CD-ROM specific commands.
what is the equivalent driver / mechanism under windows 95/98 (not wdm) and
is there a sample for this driver on one of the Microsoft ddks.
I installed the 98 ddk and did not managed to find one on there.

thanks

Just wanted to clarify some small information. The Windows NT/2000
CDAUDIO.SYS is actually a hack to get pre-SCSI2 cdrom drives to be able
to play audio discs. The problem is that SCSI1 did not define any audio
playback commands nor behaviors. Therefore, on a very small number of
drives in the Win95-Win2000 timeframe, special handling was required to
get some very few drives to be able to play audio. On most Windows 2000
machines, CDAUDIO.SYS will be listed as a filter drive, but detect(*)
that it’s not required for the device stack and just never create a
device object/attach to the stack. Then, the driver unloads because
it’s not needed. All the handling of audio playback ioctls is handled
by CDROM.SYS, whose source code is included in the DDK.

Unfortunately, I have no experience with the Win9x code base. I think
you may be looking for a file named “redbook.sys” – anyone on this list
care to correct me here? :slight_smile:

.

(*) AddDevice() checks registry to see if entry exists. If exists, and
says not required for this device, doesn’t load. StartDevice() sends
INQUIRY and similar commands, and stores results in registry. So, the
first time around, it loads. On subsequent boots, it doesn’t. Neat,
eh?
