Some applications like PCAS (and some terminal emulators) have problems sharing IRQ9 in a VDM. Since the DOS Virtual Device drivers are not loaded out of CONFIG.SYS, a new device driver VPICPARM.SYS has been added starting with Warp 3 FixPak 38 and Warp 4 FixPak 8.

To prevent sharing of IRQ9 in a VDM, add the device in config.sys: Next, in the settings for the program that requires exclusive access to IRQ9, set the DOS setting HW_SHARE_IRQ9 to ON. When you next boot your system, VDMs will not share IRQ
