 ====== DOS Laptop Audio Comparisons ======
-Here I've listed audio comparisons of various DOS laptop sound card chips, each playing the Duke Nukem 3D setup music. Most of the cards from older laptops which do work in DOS (and //not// all do) sound vaguely the same when it comes to playing back digital audio (usually if they implement Soundblaster 1.0/2.0 mono, or SB Pro / SB 16 stereo)... but the biggest difference is usually in their FM synth implementation.

 All devices using true Yamaha OPL2/OPL3 parts (YMF262 or YMF3812) will sound the same, earlier ESS chips use their (excellent) ESFM implementation, but others (including Crystal) often have their own implementation which is //not quite the same//.

+I have been unable to get the CS4281 in the Thinkpad 240X to initialise in DOS. This makes the Thinkpad 240X/240Z (and possibly the X20/X21) non-starters for DOS gaming.
