The Above Board 2 Plus is compatible with DOS and OS/2 (1.0, 1.1, 1.2, 1.3, & 2.0). Installing an Above Board 2 Plus with OS/2 1.2 HPFS system requires the latest Intel software available from Intel Customer Support. 3COM's Server Modified OS/2 version 1.1 requires the same new software. Intel has not tested Xenix with the Above Board 2 Plus, and field reports are mixed (reports of both compatibility and incompatibility). NOVELL Novell will not allow the use of an initializing ADF on a dedicated file server. An Above Board MC32 installed using the Option Diskette with Software Part Number 302477.001A uses an ADP, not an iADF, so it works fine. An Above Board MC with its normal installation will also work fine. For the Above Board 2 Plus to work with Novell, you must boot using either of the following methods: þ Boot up from the OS/2 Boot Diskette provided by Intel. When prompted, remove the OS/2 Boot disk & press a key to boot from your usual boot disk. The OS/2 Boot Diskette does not contain OS/2; it simply initializes the Above Board 2 Plus. þ Boot up from a DOS boot diskette you create as follows: - For Above Board 2 Plus use: þ Format a diskette for DOS using the /S switch þ Copy the file EMM.SYS from the Above Board 2 Plus Option diskette to the formatted diskette. þ Create a CONFIG.SYS file on that diskette containing the command DEVICE=EMM.SYS If you have the early Above Board MC32 software, you can use the following method to install the Above Board MC32, or you can get the latest Above Board MC32 software from Intel. - For early Above Board MC32 software: þ Format a diskette for DOS using the /S switch þ Copy the file ABMC32.SYS from the BACKUP subdirectory of the Above Board MC32 Option diskette to formatted diskette. þ Create a CONFIG.SYS file on that diskette containing the command DEVICE=ABMC32.SYS - Create an AUTOEXEC.BAT file which contains the commands required to start up the Novell programs. 3COMM SERVER MODIFIED OS/2 VERSION 1.1 AND ABOVE BOARD 2 PLUS With this version of OS/2, SoftSet locks up when run from the compatibility box, displaying "invalid destination drive" error. This error occurs because this operating system doesn't allow INT 13 reads or writes to the hard disk. If you have this problem, contact the Intel Customer Support BBS for the latest Above Board Micro Channel software. OS/2 V1.2 HPFS & ABOVE BOARD 2 PLUS The OS/2 Version 1.2 High Performance File System (HPFS) requires the latest version of Intel software to install the Above Board 2 Plus. DOS won't recognize a hard disk formatted for HPFS as a valid destination drive. If your hard disk is formatted with HPFS and you are having problems installing your Above Board 2 Plus, contact the Intel Customer Support BBS for the latest software. OS/2 BOOTS WITHOUT THE DOS COMPATIBILITY BOX This usually occurs because of the statement PROTECTONLY=YES in the CONFIG.SYS file. Edit the statement to read PROTECTONLY=NO, and then restart the system. OS/2 BOOTS WITH ONLY DOS COMPATIBILITY BOX This occurs when there is a shortage of extended memory in the computer. OS/2 version 1.2 requires at least 1.5M bytes of extended memory (in addition to the 640K bytes of conventional memory). OS/2 2.0 Customer Reports of compatibility with the Above Board 2 Plus and MC. We have not tested or heard of any compatibility issues with the Above Board 2 or the Above Board MC32 but do not forsee any difficulties. OS/2 Installation Note: When booting from the OS/2 2.0 Installation Diskette in a system where an Above Board 2 Plus Initializing Adapter Descriptor File (IADF) has already been installed, the Installation Diskette will first run any IADFs on the hard disk before attempting to install OS/2 2.0. In other words, the Above Board 2 Plus will be initialized and provide the memory the OS/2 installation requires without having to do anything extra. Tech Note: Although the Above Board 2, 2 Plus, and MC could provide expanded memory in the DOS Compatibility Box of earlier versions of OS/2, and even though technically it could be done under 2.0, IT IS NOT RECOMMENDED. OS/2 2.0 has a more elegant solution, and that is to use the EMM functions built into OS/2 2.0 DOS sessions. IBM TOKEN RING 16/4 AND OS/2 The first version of the Above Board 2 Plus installation software will not work. Following versions will work using the steps below. Use the Above Board 2 Plus Option diskette with Software Part Number 3001290- 004A or later and do the following: 1. Uninstall the token ring card 2. Install the Above Board and OS/2 as per the manual 3. Boot to DOS, run SOFTSET, and set the Reserved Memory Address to D000. 4. Install the Token Ring card as per FaxBack document 1522. DOS 2.X All Microchannel Above Boards are incompatible with DOS versions 2.x. DOS 3.X All Microchannel Above Boards are compatible with DOS versions 3.x. IBM DOS 4.0 IBM didn't follow the EMS specification when designing PC-DOS 4.0 and 4.01, so when trying to use expanded memory, it didn't work correctly. IBM did release a patch to remedy this. Microsoft's MS-DOS 4.1 does use EMS memory correctly. DOS 5.0 Micro Channel Above Boards are compatible with DOS 5.0. For the Above Board 2, 2 Plus and MC: As always, place EMM.SYS before HIMEM.SYS. Use the latest software version available from Intel Customer Support. With an earlier release of Intel software (EMM.SYS ver 4.0 rev C), you may receive a message from EMM saying extended memory is already in use. The NE parameter on the Device=EMM.SYS line in the config.sys file should get rid of that error, but you should upgrade to the latest Intel software. The "DOS=HIGH" command is compatible with Intel's EMM.SYS "MC" parameter. DOS doesn't load into the HMA until HIMEM loads, HIMEM loads after EMM loads, so EMM has turned off the motherboard memory before DOS loads high, so it works. For the Above Board MC32: Use DOS 5.0's combination of HIMEM.SYS and EMM386.EXE in place of ILIM386.SYS.
