A friend and I bought a pair of Latitude CPiA machines (PII-300) a while back\nfor a particular task. They had the right mix of ports and enough grunt for\n98SE, which we needed for backward compatibility with legacy DOS apps that\nrequire direct port access.\n\nI set his machine up first (clean install), and everything went to plan. Mine\nhowever refuses to expand the DOS display to full screen, even though I am using\nthe same settings.\n\nThe only difference is that his machine is 1024*768 while mine is 800*600. In\neach case I sourced the appropriate NeoMagic video driver from Dell. They\n*were* different - his specified 96699A05.EXE while mine was NEOW9806.EXE.\n\nNow my machine has TWO service tags, as I mentioned in a much earlier post\n(June 14), and I was advised to use the one on the underside of the case rather\nthan the number which comes up in the BIOS setup screen. If the BIOS tag\nreflects the mobo - which apparently is NOT the board that originated in the\ncase - surely it would be the one to use for drivers for the motherboard.\n\nMost of the work is done in DOS and the 640*480 DOS screen in native 800*600\nresolution is annoying, especially as I know that the other machine did what was\nrequired.\n\nAny suggestions?
