They emulate or restrict access to hardware. They can also add APIs, fix problems or do almost anything in VDMs (Virtual DOS Machines). Just released a vCDROM replacement that has the full functionality of the original one by IBM, but - It includes all the fixes from vCOMPAT - It won't trap on some special pointers sent by the VDM application - Checking input/output buffers for segment overflows - If a VDM application locks a CD-drive and the session is closed afterwards, the CD-drive is automatically unlocked - Workaround for OS2CDROM/CD-ROM IFS bug, that doesnt allow getting handles for a drive, if no CD is inserted - Workaround for a buffer-overflow problem, when using a special FSCTL on CD-ROM drives. - 100% rebuild, 95% assembly - Larger than the original version, because I didn't do pseudo-optimizations (like the original one) that also were responsible for the ring-0 traps due mishandling of pointers. New vCOMPAT v0.32b contains the following changes: - Another CD-ROM specific inaccuracy in VDM. Thanx to Max Alekseyev for pointing this out (This bug is actually just worked around, it's 100% fixed in my new vCDROM resulting in one device header per CD-ROM drive) - Support for vCDROM replacement (disabling of CD-ROM related patches, which will safe realmode-memory) - Reworked the realmode injector, uses VDD-space and much less V86 memory now Downloadable from: http://ecomstation.ru/kiewitzsoft/vdd-vcdrom.php and http://en.ecomstation.ru/kiewitzsoft/vdd-vcompat.php Source is also available, but only for people that are really interested in. But I won't give out the source for people trying to fix the braindead VDM from Windoze eXPeriment.
