Tech Note:Uses I/O port 208. HERCULES HERCULES COLOR BOARD Compatible with Above Boards. Parallel port address = 378h. (BECOMES LPT1: ONLY IF MONOCHROME CARD IS NOT PRESENT!) HERCULES GRAPHICS & ABS Compatible with ABPC, ABAT, AB 286, and AB PLUS. Tech Notes: Parallel port address = 3BC. (ALWAYS LPT1: IF PRESENT IN SYSTEM!) Some customers report the following Symptom: older IBM AT's would lock up on a warm boot when an AB was providing expanded memory. This was caused by the EGA BIOS ROM in old AT's. Adding "EXPF=C400" solves the problem. HERCULES GRAPHICS PLUS *FIELD REPORTS* of compatibility with Above Boards. Tech Notes: This video board from Hercules supposedly speeds up scrolling in Word 3.0, speeds up Framework II, and improves Lotus 123 by adding a pop-up menu, speeding up scrolling, and increasing the amount of data per screen. It has one problem -- you can't use a mouse with the Hercules driver that allows these features. No AB problems have been reported with this board in general, however, if any of Hercules' RAM font drivers are being used, then Quikbuf cannot use the pop-up menu and must be installed with the `o' parameter. If no RAM font drivers are being used, then the pop-up should work just fine with the `h' option of Quikbuf. If Microsoft WORD is being used with the /h parameter, then use the `o' option for Quikbuf. HERCULES VGA *FIELD REPORTS* of compatibility with Above Boards. Tech Notes: In one customer's system, with AB Plus base I/O address set to 258 the AT gave "Parity Check 2 ?????" on Warm Boot ONLY. No error on Cold Boot or when SETBOARD rebooted the system. Happened with EMM loaded or not. Changed I/O address on AB Plus to 208 and it worked. General Info: 8 bit board, no switches or jumpers. It "appears" to be in autodetect mode by default, which can only be changed by loading device drivers on boot, (that's how the customer understood it). HERCULES HGC FULL UTILITY & QUIKBUF Install HGC FULL before QUIKBUF. IBM IBM COLOR GRAPHICS BOARD Compatible with Above Boards. IBM EGA & ABS Compatible with Above Boards. Tech Notes: This EGA takes 16k of reserved memory space, from C000-C3FF which might be an issue with some older network adapters and expanded memory. IBM EGA & AT W/ ENHANCED 5250 EMULATOR Cannot use ANY 128K memory expansion board in AT system when EGA is used with Enhanced 5250 Emulator software. Patch in 5250 software manual will cure the problem. IBM EGA & QUIKBUF With QUIKBUF software that shipped with EMM versions earlier than 4.0, it will be necessary to disable the QUIKBUF pop-up menu when using an EGA Adapter. (Put `o' in quikbuf command line.). With QUIKBUF software that shipped with versions 4.0 and higher, a parameter was added so the pop-up menu can be supported, (put an "e" on the command line). IBM MONOCHROME BOARD Compatible with Above Boards. Tech Note: There's a parallel port on most versions of these video cards. Parallel port address = 3BC. (ALWAYS LPT1: IF PRESENT IN SYSTEM!) IBM VGA & AB PLUS The IBM VGA board uses the address space from C0000-CBFFF. Even though the board uses the entire C0000-CBFFF range, the memory locations from C8000-CBFFF appear to be unused by the Above Board programs INSTALL, SOFTSET, and EMM. It is therefore necessary to manually edit the EMM.SYS device driver line to relocate the expanded memory page frame to CC00 or D000. MG VGA (1024 X 768) 8514 COMPATIBLE We have customer reports of compatibility with the MG VGA board itself. However there is also a driver provided with this board that runs in Expanded memory for use with Autocad. We have a report that this driver may not work with our board in some fast 286 computers. The MG VGA uses registers 2E8 to 2ED, and has a BIOS switchable between C800 to CA00, or D800 to DA00. This VGA board is 16-bit through the Data Bus, but only does an 8-bit access through the ROM, so there is no need to put this board into an 8-bit mode or into an 8-bit slot. NEC MONOGRAPH BOARD *FIELD REPORTS* of compatibility with Above Boards. Tech Notes: Compatible with ABs using Classic Bus (EMM 4.0 rev C) with EXPF=D000 to confine EMM's page frame. AB Plus and original Plus EMM 4.0 using EXPF=D000 also work. Incompatible with EMM 4.0 Rev A and B, will work with EMM 3.2. The original EMM 4.0 does a check through reserved memory which writes over the Monograph ROM information, causing it to lock up. Classic Bus EMM, May 89, combined the AB 4.0 Rev B with the AB Plus 4.0. Original Plus EMM 4.0 works only on AB Plus boards. NEC VGA 16BIT *Field Reports* of limited compatibility with Above Boards. There are no compatibility issues at all if the Above Board is just providing extended or conventional memory. If the AB is providing Expanded memory, there will be a 16bit reserved memory access conflict, and the NEC board would need to be put into 8-bit mode. If the NEC video adapter did a true 16bit access of reserved memory there would be no need to put the NEC adapter into 8bit mode, but since this adapter fluctuates between 8- and 16-bit reserved memory accesses there isn't another work-a-round. NUMBER NINE GRAPHICS BOARD *Field Reports* of compatibility with Above Boards. Tech Notes: Even though this graphics board is supposed to be an 8-bit board, it acts as if it is running into a 16bit reserved memory access conflict with this card installed. SYMPTOM: When AB is in the system (with or without EMM), the #9 board isn't recognized. SOLUTION: Tell Setboard 10 or 12 MHz. ORCHID ORCHID VGA PLUS *FIELD REPORTS* of limited compatibility with Above Boards. This 16-bit VGA board causes a 16bit reserved memory access conflict with an Above Board providing expanded memory, since this VGA doesn't access reserved memory in a true 16bit fashion (it fluctuates between 8- and 16-bit reserved memory accesses). This adapter has no switch for 8-bit ROM BIOS. To work with an Above Board providing expanded memory, you must install this video board in a 8-bit slot. Also, you MUST add EXPF=C800 (assuming there's no other ROMs present) or the system will lock up when EMM tries to load! Above Boards providing Extended memory work fine with these video cards. VGA MEMORY USAGE Some general info: VGA's in general use ALL of A0000 to BFFFF for video data. These guys tend to be in EGA mode most of the time because software has to be rewritten to use REAL VGA capabilities. There are more and more REAL VGA applications being written daily. VGA mode itself has several modes i.e. 640 x 480 w/sixteen colors, 320 x 200 w/256 colors (WOW the shading) and some others. The VGA board has TWO eproms located at C0000 to C7FFF which in effect is an extention of EGA (EGA used C0000 to C3FFF) so we can forget about the lower half of the C0000 area for use when providing expanded (LIM EMS) memory. Most VGA boards occupies (not necessarily always uses) the area from A0000 to C7FFF (160k!). IBM 's VGA in the PS/2 machines don't occupy the C0000 to C7FFF area because the BIOS supports it directly. ORCHID PRODESIGNER PLUS VGA *Field Reports* of compatibility with Above Boards. There is one potential conflict when the Above Board is set up to provide expanded (LIM EMS) memory: ώ This VGA card uses a 32k area that the Above Board can use, from C0000 - C7FFFh. HERCULES HPRINT UTILITY & QUIKBUF The Hercules HPRINT utility uses Shift-PrtSc key combination, which interferes directly with the QUIKBUF pop-up menu (QUIKBUF also uses Shift-PrtSc). If you want to use the QUIKBUF pop-up menu, put the QUIKBUF command (with the Hercules option) before HGC PRINT command in the AUTOEXEC.BAT file. Then use the HPRINT sequence of Shift-PrtSc- Spacebar to pop-up the QUIKBUF menu. NOTE: HPRINT uses Shift-PrtSc-0 or Shift-PrtSc-1 to print graphics screens. Using one of these on a text screen will lock up the computer. HPRINT only works with Epson RX, MX, or IBMGraph printers. Using another printer may also lock up the computer.
