STANDARD VIRTUAL DEVICE
Windows include a wide variety of virtual devices to support common hardware
devices and installable software, in some cases, a virtual device may need to
be modified to accommodate new features or to support nonstandard hardware.
Windows provides many ohter devices that are not intended to be modified, but
help support other virtual devices. For example, many virtual devices use the
services provided by the V86 memory manager(V86MMGR) and the virtual programmable
interrupt controller device (VPICD) to reserve V86 mode memory and enable
interrupt requests (IRQs) for their hardware.
To help with you develop virtual devices, the Microsoft Windows 95 Device Driver
Development Kit includes source sode for fully operational virtual devices.
