I have checked the manuals for QEMM/Manifest and could not find what this is. By doing a "strings" on it, it appears to me to be another driver for windows 3.0. If anyone knows what it is, or where I can find out, please let me know. Don't just say RTFM, tell me where, since I already DID RTFM. Thanx in advantz. -- .............................................................................. Theodore S.

This is a Virtual Device Driver that was provided by Microsoft to 3rd Party Memory Managers. Whenever Windows 3.0 is started up in 386 Enhanced Mode this Virtual Device Driver ( Microsoft calls it LoadHi ) will be loaded by QEMM-386. This virtual device driver will fix problems in instancing and supporting TSRs loaded between 640-1MB (i.e. UMB memory) via QEMM-386. If you had 386MAX they call theirs 386MAX.VxD. Same concept. The LoadHi VxD distributed by Microsoft to them was given in the form so that vendors could change it. The one that Quarterdeck shipped with 5.11 was buggy and caused all kinds of problems under certain circumstances. It mostly caused problems for networks that were also using VxD's to support their networking. The WINHIRAM.Vxd shipped with 5.11 changed the way ( actually incorrectly ) some of the Windows kernel memory management calls returned. Most of these calls that failed were only used by other Virtual Device Drivers whose purpose was to bridge Windows Applications or DOS applications running in Virtual Machines to software such as networking which was loaded before Windows. I know all of this because I reported most of the problems to Microsoft, QuarterDeck, and Qualitas since I was responsible for modifying our networking to work with Windows 3.0. There was an article I believe in PC Week or some PC trade rag that talked about this VxD. > > Thanx in advantz. > -- JJ
