SCSI DVD-RAM in DOS

I have a Panasonic DVD-RAM Matshita LF-D200 SCSI connected to the Toshiba laptop Tecra 8100 through a PCMCIA 16 bit SlimSCSI Card Adaptec APA-1460-A.
In Windows 2000 Pro, I can access the DVD RAM without problem.
In DOS, the DVD RAM is recognized correctly and it is given the SCSI id number 6.
However, after that I get a message:"Finding a drive letter for the DVD RAM".
Then"NO drive letter given". And the drive cannot be accessed.
Can you help?
Thank you,
Daniel Bessis
P.S. The CDs in the drive are formatted in FAT 16 bit.

What are the circumstances leading to the SCSI ID6 beeing assigned?  Are you using card, and socket services for the sockets, and the correct ASPI layer for the card?  How about drivers to include MSCDEX.EXE for the drive?

Post your Autoexec.bat, and Config.sys files you are using.

You are approaching this with the right idea, but the wrong drivers.  You need to use the Panasonic/Matsushita based drivers instead of the Adaptec drivers.  You may not even need card and socket services.  Looks like you need the following files from the accompanying CD.

DVDHOOK.EXE
MSDRVR.SYS
MCDPD.SYS

Jason,

Thanks to your help, everything works fine. Just one more question. Is it better to use ASPI8DOS.SYS rather than ASPI2DOS.SYS? Is one an update of the other one?

No.  They are for two different SCSI cards.  ASPI2DOS.SYS seems to be correct for your card.  ASPI8DOS.sys is for Adaptec 29XX series cards.

I am submitting this as an answer as it seems I have solved your problem.

Thank you, and glad to help.
