Note that there is a bug with the Windows 95/98/NT TSD (Type Specific Driver) such that these operating systems have trouble paging to removable devices. Specifically, the PCI bus caching requires the code to do an in* after and out* to flush the bus cache, and the TSD that Microsoft provides doesn't do this. I found this out after installing Windows 95 and NT on JAZ cartridges, and then having problems installing Visual InterDev (their full "professional" developement tools suite) and seeing very odd behaviour trying to install Visual SourceSafe (the revision control system) and Visual J++. Eventually they refunded my support incident when I located the assembly code error in their driver (using WinICE) and pointed it out to them. FreeBSD needs something like WinICE...
