Nathan Woodruff 2008-09-17 23:40:15 | I am writing a device driver for an OPTO-22 PCI-AC5 card....

There is a windoze driver for the card. My only problem is the memory for this card is allocated in the 3-4Gigabyte range by the PCI memory manager.
I have searched hi and low for any information on DPMI programming for OS/2 and I have found none. The driver is mostly complete except getting access to the memory above the 1 meg limit of 286 code imposed for device drivers.
If you could provide me with any info or even some examples of DPMI programming I would gladly finish the driver and free it along with the source code into the OS/2 domain.
