### OS/2 ISA/EISA Floppy Driver

Driver Description:

The ISA/EISA floppy device driver is the diskette driver for ISA/EISA bus systems. The driver obtains diskette information from the host system BIOS. If the information provided to the host system is incorrect, or if the BIOS does not support a third or fourth floppy drive, it might be necessary to provide this information on the IBM1FLPY command line.

Compilers/Assemblers Required:

           Microsoft MASM 5.1  (supplied with the DDK)
           Microsoft C 6.0

Build Instructions:

1.Set the environment variables so the correct tools are picked up during the build.

    e.g., SET PATH=<drive>:\DDK\TOOLS;%PATH%

Where <drive> represents your DDK installed drive and DDK represents the DDK installed directory. On the CD-ROM, the TOOLS directory path is DDK\ TOOLS.

2.Before the FIRST build is attempted, run (only once) the COPYC60.CMD REXX command file in the DDK\TOOLS directory. This command copies the set of needed files from your copy of the Microsoft C 6.0 compiler to the proper directories under the DDK base directory.

    e.g., COPYC60 <MSCdrive>:\'MSC60' <drive>:\DDK

Where <MSCdrive> represents the Microsoft C 6.0 installed drive and 'MSC60' represents the Microsoft C 6.0 installed directory, <drive> represents your DDK installed drive and DDK represents the DDK installed directory.

To build the ISA/EISA Floppy Driver:

3.Change the directory to BASE\SRC\DEV\DASD\IBM\IBM1FLPX.

4.Invoke NMAKE on the resident makefile.

Files Created by Successful Build:

         Directory:  \DDK\BASE\SRC\DEV\DASD\IBM\IBM1FLPX
