From: Colin Ian King <cik@ukc.ac.uk> To: ejs1 Subject: MSCDEX, NFS and Lots of CDROM Databases Message-Id: <"leeman.yor.099:24.01.93.16.19.11"@york.ac.uk> Status: RO MSCDEX Interrupt 2f Usage for Various Databases. I have written a small TSR that captures all MSCDEX interrupts and logs them, then passes the control over to MSCDEX. The following table shows which function request command codes are passed to MSCDEX. Databases marked `None' for the AL function request command codes are hence easy to run under NFS. Titles using function request command codes 00 and 0D can probably be run with MXSUB. The others are more difficult..

I have re-written MXSUB for my Borland C++ compiler, and I hope to modify it to allow me to add or remove CD-Drives from the drive list, making it more dynamic and flexible. I hope to add function request command codes 01h,0Bh,0Ch,0Dh soon to my version of MXSUB. Colin King, Templeman Library, University of Kent.
