The Above Board PC can provide conventional and expanded memory in these systems. The Above Board PC are NOT COMPATIBLE with 80286, i386CPU-, and i486CPU- based computers and many TURBO XT compatibles. The Above Board PC was designed to work at a speed of 4.77MHz like the original IBM PC and XT. These installation instructions assume that you are using the Above Board installation software dated 6/90 or later. The latest Above Board software is always available on the Intel BBS for anyone to download. ADDING MEMORY TO THE ABOVE BOARD PC You can use either 64K-bit chips or 256K-bit chips on the Above Board PC, but you can't use both types at the same time. For a list of chips that Intel has verified, refer to FaxBack Document #1014, "Classic Above Board Memory Chip Compatibility." You need to use 200-nanosecond chips or faster, (such as 150ns or 120ns, etc). You must fill each column to which you add chips, (nine chips to a column). Leave no partially filled columns. Fill the columns in the order shown in the following diagrams.

If you don't add conventional memory with the Above Board, you don't have to change the computer's switches. The following figures show the settings for IBM PC-1s and PC-2s if the Above Board provides conventional memory up to 640K bytes: ÚÄÂÄÂÄÂÄÂÄÂÄÂÄÂÄ¿ PC-1 (640K) ³Ü³Ü³Ü³Ü³ ³ ³ ³ ³ Note: The PC-1 ROM BIOS allows ÀÄÁÄÁÄÁÄÁÄÁÄÁÄÁÄÙ 544K bytes maximum. 1 2 3 4 5 6 7 8 ÚÄÂÄÂÄÂÄÂÄÂÄÂÄÂÄ¿ PC-2 (640K) ³ß³Ü³ß³ß³Ü³ ³ ³ ³ or PC-1 with ÀÄÁÄÁÄÁÄÁÄÁÄÁÄÁÄÙ upgraded BIOS 1 2 3 4 5 6 7 8 NOTE: PC-2s have a "B" stamped on their back panel, PC-1s do not. SETTING UP EXPANDED MEMORY The SOFTSET program will install the software necessary for EXPANDED memory. SOFTSET copies necessary files to your system disk and adds commands to your CONFIG.SYS and AUTOEXEC.BAT files. You must be using DOS 3.0 or later to run SOFTSET. SOFTSET must be run from a floppy disk. SOFTSET saves your original CONFIG.SYS and AUTOEXEC.BAT files under the names CONFIG.OLD and AUTOEXEC.OLD. To start SOFTSET, boot your computer to a plain DOS boot disk that doesn't have a CONFIG.SYS or AUTOEXEC.BAT file on it. This is to ensure that no TSR's or other programs are loaded that may interfere with SOFTSET. Insert your Above Board Installation diskette into drive A and at the DOS prompt type A:SOFTSET Follow SOFTSET's directions and answer the questions, SOFTSET does the rest. SOFTSET will add the device driver EMM.SYS to your CONFIG.SYS file. If you chose to install the RAM disk on the SOFTSET installation options menu, the device driver QUIKMEM2.SYS will be added to the end of your CONFIG.SYS file. If you chose to install the print buffer, the command QUIKBUF2 will be added to your AUTOEXEC.BAT file. EMM.SYS DRIVER PARAMETERS, ABOVE BOARD PC AND PS/PC The SOFTSET program will automatically install the EMM.SYS Expanded Memory Manager device driver and its parameters. The parameters are given here so that you can manually install the software and manipulate the page frame address in cases where there is a memory conflict with other add-in boards in the system. Please remember, these parameters are for the drivers from the LATEST Above Board Installation Software dated 6/90 or later with EMM.SYS rev 4.0D. The latest Above Board Installation Software is always available on the Intel BBS for downloading, ph. (503) 645-6275. EMM.SYS: To use expanded memory on your Above Board PC or PS/PC, the EMM.SYS command line must be the FIRST line in your CONFIG.SYS file: DEVICE=EMM.SYS PC i/o-address [EXPF=x] [ND] [NP] [VI] The order of the parameters does not matter. The parameters are separated by a space and they can be in upper or lower-case. i/o-address, (2x8, REQUIRED PARAMETER) The "i/o-address" parameter specifies which base I/O address the Above Board will occupy. This should match the I/O address set with switches on the Above Board. The I/O addresses of other Above Boards providing expanded memory should also be included. Assign a unique I/O address to each Above Board. No boards in your computer can share I/O addresses. Below is a list of valid I/O addresses for the Above Board PC and PS/PC: I/O Address 208 218 258 268 2A8 2B8 2E8 EXPF= (EXPanded First, OPTIONAL PARAMETER) The EXPF= parameter specifies the beginning of the 64K-byte page frame needed for LIM 4.0 expanded memory. The following values are valid: EXPF=C400 C800 CC00 D000 D400 D800 DC00 E000 Example: You're installing the Above Board in an IBM XT. The Above Board is using I/O address 258. You want EMM to begin looking for an available page frame in reserved memory that is not in use by other add- in boards. In this example we'll imagine the other add-in boards are using reserved memory addresses C000 to C7FF. The EMM.SYS command line would read: DEVICE=EMM.SYS PC 258 EXPF=C800 SETTING UP RAM DISKS QUIKMEM2.SYS: To set up a RAM disk in expanded memory, add this line to the end of your CONFIG.SYS file. DEVICE=QUIKMEM2.SYS x The "x" parameter specifies the size of the RAM disk in K-bytes and must be at least 16. Values that are not multiples of 16 will be rounded up to the next higher multiple of 16. The maximum size of the RAM disk is 8M-bytes, (8192K). Example: To install two 512K RAM disks in expanded memory, add the following two lines to the end of your CONFIG.SYS file: DEVICE=QUIKMEM2.SYS 512 DEVICE=QUIKMEM2.SYS 512 The drive letter assigned to each RAM disk is displayed when the computer is started. There are no parameters to manually assign a different drive letter to the RAM disk(s). DOS automatically assigns the next available drive letter to the RAM disk(s). SETTING UP A PRINT BUFFER QUIKBUF2.COM: To set up a print buffer in expanded memory, the following line must be added to your AUOTEXEC.BAT file: QUIKBUF2 PC x d t The "x" parameter specifies the size of the buffer in K-bytes and must be 32 or greater. Any value that is not a multiple of 16 is rounded up to the next higher multiple of 16. 16K of the print buffer is reserved for the pop-up menu. The "d" parameter specifies the type of display adapter your computer is using. Choices for the "d" parameter are: M - IBM Monochrome Adapter H - Hercules Monochrome Graphics Adapter G - CGA adapter E - EGA adapter V - VGA adapter O - Other adapter: Used if the pop-up menu isn't being displayed properly. The "O" parameter disables the print buffer command menu but the print buffer will still work. The "t" parameter indicates the type of port to be buffered. Valid choices are: P - Parallel port, (LPT1, LPT2, LPT3) S1 - Serial port, (COM1) S2 - Serial port, (COM2) If you choose "P", the first parallel port you print to will be the buffered port. If you omit the "t" parameter, the print buffer defaults to parallel. Example: To create a 256K print buffer in expanded memory on an IBM XT with an IBM Enhanced Graphics Adapter, and you want to buffer the first parallel port you print to, use the following command: QUIKBUF2 PC 256 E P ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ End of file Intel FaxBack # 1210 November 9,1992
