vxd support?

[Osvaldo Fornaro]

Hi,

I were far from the project for a while, so sorry if this topic is trivial, 
but I wish to use a parallel port scanner with wine. Under Windows, appears a 
device to treat the parallel port as a SCSI port, but is based on a VxD 
archive, and wine don't find it.

Is there any solution to deal with VxD or not yet?

Thanks in advance.

No, and ther most likely never will be.

VxDs are more or less equivalent to Linux's kernel modules: most need
direct access to the hardware, must run in ring 0 (the most priviledged
level of the processor) and use a separate API (the DDK API rather than
the Win32 API). So Wine does not deal with VxDs.
   Maybe we should add a section in the Wine User Guide to list what
Wine does not do right after 'Wine capabilities':

Does the scanner use it's own's VXDs or does it use the system parallel VXD?
In the latter case, supplying the needed functionality might be possible.

I suppose that are propietary drivers, eppscsi.vxd or something like that. 
However, such files there is not exist in a windows instalation of the 
scanner. It sounds like the file is unpacked or renamed during execution.

If there exist any hope, I will try to install the scanner again (vmware 
deals fine with the scanner, but is so heavy...)

Thanks,
