After installing Win32s in your Windows 3.x system, you may receive a page fault error message that reads, ""FMPRO30 caused a Page Fault on Module WIN32S16.DLL @ 0005:0632". This message points towards a particular incompatibility with your machine and Win 32s.
Generally, there are three possible incompatibilities: video driver bios, printer driver bios and your machine's system bios. This can usually be corrected by updating the bios for the particular device driver.
Specifically, in some Dell PC- Compatible machines, the new Dell A05 bios has been known to cause Page Faults within Win 32s. However, the Dell A02 bios appears to work fine.
