Well, just steal some generic PCX code and either
load it into a buffer or draw it with DirectX. All
the DOS game programming books and lots of pages
like cdrom.com or simtel.net will have the code.

You mean like this????

// data for the pcx file is decompressed and expanded into a secondary buffer

// buffer later. also the header and palette are loaded
