Program: The SK_HGC.COM TSR is used to support operation of ARABIC.COM/ HEBREW.COM with the Hercules Graphic Card series of video adapters. It is provided for compatibility with ADOS 3.30/HDOS 3.30 only. This file must be loaded immediately after ARABIC.COM/HEBREW.COM to insure correct operation with these devices.
Notes: This call is made by the SK_HGC.COM TSR for HGC and HGC/RAMFont graphics adapters when it has successfully detected an Arabic/Hebrew issue of MS-DOS via INT15h/6700h/BX=FFFFh to ensure it runs on the correct version of Arabic or Hebrew MS-DOS.. At some unknown offset in the buffer it contains a flag indicating if a HGC or HGC/RAMFont adapter is present or not.. ARABIC/HEBREW does not operate with Monochrome Display Adapters (MDA) and the Hercules Graphic Card Plus (HGC+). ARABIC/HEBREW does operate with Hercules Graphic Card (HGC) with a burnt-in ROM/EPROM font (many HGC cards, even the highly integrated ones, allow for this kind of user customization), though this is not officially supported.. In some pre-1987 IBM XT/AT and compatibles, the Hercules Graphic Card Plus operates like a MDA card. This hardware limitation prevents ARABIC/HEBREW from running on this combination of hardware.
