BOARDS THAT CAUSE THE COMPUTER TO BEEP Boards such as IBM EGA, QUAD EGA+, and VEGA EGA may cause the computer to power up in 40-column mode and to sound one long and three short beeps. The EGA BIOS tests running at 16 MHz causes this to happen, and it does not indicate a problem with either the EGA or the computer. You can return the computer to 80-column mode and reset the EGA by adding the Inboard 386's INBRDAT.SYS command with the EGASIZE=x parameter to your CONFIG.SYS file. With Inboard 386 software versions 1.0 and 1.1, you can return the computer to 80-column mode and reset the EGA by adding the following commands to the AUTOEXEC.BAT file: EGA x (where x = number of in K bytes of memory on MODE 80 of the EGA board: 64, 128, or 256) The screen will display 40-column mode until these commands are executed. Both the MODE.COM and EGA.EXE programs must be either in the root directory or in a directory included in a PATH command in the AUTOEXEC.BAT. BOARDS THAT DON'T CAUSE THE COMPUTER TO BEEP The following boards do not cause the computer to beep: þ AST EGA þ ATI EGA Wonder board þ Everex autoswitch þ Paradise autoswitch AST RAMPAGE/EGA Customers report this video board is compatible with the Inboard 386 if the EGA board has an upgraded ROM chip. If you orient the board so the chips face you and the metal mounting bracket is to the right, you'll find the chip in the upper right part of the board. A white sticker on the face of the chip lists one of two part numbers: "AST 1986 107000-391C" is the non-upgraded ROM, and "AST 867000-391D" is the upgraded ROM. AT&T TARGA There are several versions of this board. Only the versions later than November 1986 are compatible with the Inboard 386. To determine which board you have, look for a small sticker with the blue AT&T logo and blue Globe located near a large sticker with a switch-setting chart. Only the latest versions have the small sticker. AT&T can upgrade earlier versions of the board for about $70. ATI EGA WONDER BOARD The Inboard 386 discontinued IEMM386 software doesn't work with this board when it's in Autoswitch mode. The ILIM386 software available on the Intel BBS should work fine. If you are still using the IEMM386 driver, either upgrade to ILIM386 or disable the Autoswitch feature when using IEMM386. COMPAQ VIDEO GRAPHICS CONTROLLER This board is compatible with the Inboard 386. However, when the COMPAQ VGC board is used in a computer with a Microsoft serial mouse or Microsoft bus mouse, problems can result from the interaction between the video BIOS and the mouse driver. The problems vary with software configuration and computer type, but they may include data loss or corruption on the hard disk or floppy disk. This is not a problem with the Inboard 386. COMPAQ knows about the problem and has software (called INT10VGA.SYS) to fix it. Call COMPAQ to get INT10VGA.SYS. HERCULES COLOR BOARD Customers report that this board is probably compatible with Inboard 386, but one report indicates a 6-MHz IBM PC AT locked up with the Hercules Color board and Inboard 386 installed. Intel has not tested this combination. HERCULES GRAPHICS PLUS Intel tested this board with Inboard 386, and they are compatible. IBM PROFESSIONAL GRAPHICS ADAPTER (PGA) Intel has verified that the Inboard 386 is incompatible with this graphics board. IBM VGA Customers report the computer sounds one long and three short beeps at power-up with the Inboard 386 installed, but the VGA board is compatible and works fine. The beeps are usually caused by video BIOS tests running at 16 MHz; they don't indicate a problem with either the VGA or the computer. PARADISE AUTOSWITCH The Inboard 386 discontinued IEMM386 software doesn't work with this board when it's in Autoswitch mode. Possible solutions are to disable the Autoswitch feature when using IEMM386 or remove IEMM386 and use another memory manager, (IEMM386 was replaced by ILIM386, which is available on the Intel BBS). PARADISE VGA Customers report that this video board is compatible with the Inboard 386. Tech Note: This board has a larger ROM BIOS area than most VGAs, it uses addresses C000-CBFF, which may be an issue when setting up expanded memory. QUADRAM QUADHPG (HIGH PERFORMANCE GRAPHICS) This board is compatible with Inboard 386. This board uses the Intel 82786 graphics coprocessor and has a piggyback board that allows the QUADHPG board to emulate EGA. You cannot use EGACACHE with this board. SIGMA MAXIMIZER AT One customer reported that Inboard 386 computers won't warm boot with this board or recognize its extended memory. TALL TREE JLASER The Inboard 386's IEMM386 software is incompatible with the JLAZER board. ILIM386 software should work, so if you are still using IEMM386, upgrade to ILIM386. VERTICOM H-256 GRAPHICS CONTROLLER Customers report that this board emulates an IBM PGA, a board with which the Inboard 386 is incompatible. However, a dealer has reported testing these high resolution graphics controller boards, and the Inboard 386 worked fine. Intel has not confirmed the dealer's findings. VEGA VIDEO 7 DELUXE The Inboard 386 IEMM386 software doesn't work with this board when it's in Autoswitch mode. ILIM386 software should work, so if you still use IEMM386, either upgrade to ILIM386 or disable the Autoswitch feature when using IEMM386. You could also remove IEMM386 and use another board (such as an Above Board with EMM) for expanded memory. The Video 7 board uses addresses A000-BFFF and C000-C3FF and IRQ 2. VEGA VIDEO 7 FASTWRITE VGA One user reports compatibility between this board and Inboard 386 after turning Switch 4 on the Video 7 board to "on". Video 7 suggested this, though the manual states this switch does nothing and must remain off. ZENITH Z-449 This board won't work with the Inboard's EGACACHE parameter. This board has an autoswitch feature. If autoswitch is on, warm boot will not work. Therefore, turn the Z-449 board's autoswitch off.
