[syslinux] Custom com32

[Coe, Colin C. (Unix Engineer)]

Many thanks!  I ended up working out what needed to be done.

Another question, how can I call fscanf from within my COM32 module.
When I compiled the module I got linker errors.  Any ideas?

I wanted to use fscanf to read a csv file of "model,bios" values instead
of hardcoding them into the COM32 module and having to recompile when
different hardware is used.

Thanks

You're probably better off using "Run kernel image" (AX=0016h).  The 
kernel image would me "memdisk" and the command like something like 
"initrd=xw9300_2.09.img".
