I don't have a source for an mscdex earlier than 2.20, sorry. Have you tried v2.2*1*? It seems to be the best of the later crop. Have you also checked any dip switches or other settings on the drive itself and looked for possible IRQ or DMA conflicts? If in doubt, strip all possible expansion boards out of your system; it sounds hairy but only takes a few minutes. Or do you have access to another CPU that you could try the drive on to be sure the controller and drive function normally elsewhere? Hope there's a clue there somewhere!
