BEEPS This error occurs if the Inboard 386/PC detects the computer supplying over 256k of memory. The Inboard 386/PC can only replace the system board memory if 256k (or less) is being provided by the system board. If you receive the SOS beep when the computer appears to be configured properly, toggle the system board switches several times and then restart the computer. In some "compatible" computers the switches on the motherboard that would correspond to the IBM memory configuration switches aren't even hooked up. It may be necessary to check with the system board manufacturer as to how to properly disable memory to 256k (or lower). CAN'T FORMAT FLOPPY If you have this problem, add the NOCACHE parameter to the INBRDPC.SYS command. You can also try the FDWAIT parameter. CONTINUOUS POST SYMPTOM At power up, if Switch 1 on a PC XT system board is ON, the computer will count to 640K bytes and then count again, continuously. Turn Switch 1 OFF. HARD DISK ACCESS PROBLEMS The ILIM386.SYS DMA=xx parameter can help with drive access problems with some hard disk controllers. The default DMA transfer area size is 64K bytes. Try other values, starting with DMA=32. INBOARD 386/PC AND HEAT The InBoard 386/PC can draw up to 20 Watts of power. This much power draw inside a PC system can cause heat-related, intermittent failures from both the InBoard 386/PC and other components. To insure the best operating environment, make sure the InBoard 386/PC has as much open space around it as possible. If it is not possible to move the other cards in the system away from the InBoard 386/PC, it may be necessary to add an additional cooling fan. COLDBLUE If you have heat-related problems with Inboard 386/PC installed, the COLDBLUE add-on cooling system for IBM PCs and XTs may help. COLDBLUE snaps to the front of the system unit behind the cover's front ventilation slots. COLDBLUE consists of side-by-side cooling fans that force air across the expansion cards at a claimed rate of 25cfm. Intel hasn't tested this product, but you can contact COLDBLUE Corp. at (512) 341-6155. PC POWER & COOLING HEAVY DUTY POWER SUPPLY PC Power & Cooling makes high capacity power supplies with large fans for IBM XT and AT and COMPAQ PORTABLE systems. Here's their address: PC Power and Cooling, PO BOX 518, Bonsall, CA 92003-0518 (619) 723-9513 FAX: (619) 723-0075 RADIO SHACK FAN One customer reported using a Radio Shack 3" x 3" external cooling fan with Inboard 386/PC. The user reported the fan worked great and fits closely against the back of the computer. Intel has not tested this product. LOCKUPS WITH CAD PROGRAMS Some programs will recognize a math coprocessor even if the math coprocessor switch is set incorrectly. Other programs won't, so make sure the switch is set correctly. MISSING OR WRONG DISK AND MANUALS If you receive the wrong diskettes or manual with your Inboard 386/PC, do the following: 1. Note whether the Inboard 386/PC box was unopened before you bought it. 2. Gather the following information: a. Serial number of the Inboard 386/PC b. Date on outer label of Inboard 386/PC c. Name and address of the dealer who sold the Inboard 386/PC d. List of missing items 3. Contact Intel Customer Support PRINTER PRINTS UNWANTED CHARACTERS If this happens, set the Inboard 386/PC to Speed 1. One user with an Inboard 386/PC in an IBM XT reported that a NEC 8800 Spinwriter printed unwanted characters unless the Inboard 386/PC was set to Speed 1. This customer then installed a print spooler program called Softbytes, and the printer printed fine at all speeds. SLOW HARD DISK ACCESS OR READ ERRORS Most disk drive manufacturers and dealers set drives for a 3:1 interleave. This could cause very slow hard disk access or read errors. More appropriate values are 4:1 or 5:1. INBOARD 386/PC DRIVER ERRORS ON SOFTWARE WARMBOOTS ILIM386 version 4.07 "survives" a software generated warmboot, leaving the processor in virtual 8086 mode. Because of this, INBRDPC.SYS will display an error when it tries to load. The error states that "80386 control software has already been loaded". To boot successfully, reset your computer using one of the following methods: þ Press CTRL-ALT-DEL keys at the same time. þ Press the reset button on your computer (if available). þ Turn the power off, wait 30 seconds then turn it back on. OUT OF ENVIRONMENT SPACE The DOS 3.x environment may be up to 32K bytes long. During power on, COMMAND.COM receives a default environment size of 160 bytes. This can fill up quickly, in which case DOS displays the message "Out of environment space." If you use DOS 3.1 through 3.3, you can increase the environment size by including the following command in the CONFIG.SYS file: shell=[d:][path]command.com /p /e:xxxx In DOS 3.1, xxxx is the # of paragraphs (16 byte blocks) in the environment. The allowable range is from 10 to 2048. In DOS 3.2 and 3.3, xxxx is the actual # of bytes in the environment. The allowable range is from 160 to 32,768. 1701 ERROR IBM PC XTs will report a 1701 Hard disk controller error on power up if the power has been left off for less than 15 seconds and if the cold boot follows a warm boot. This happens even without the Inboard 386/PC installed. The fixed disk BIOS causes this error when it fails a test when the warm boot flag is still in memory on a cold boot. Powering up quickly right after a warm boot doesn't give the RAM time to discharge and lose the warm boot flag. A055 201 MEMORY ERROR If you receive a A055 201 Parity Check 2 message, make sure the power supply is rated for 100 watts or greater. This error also occurs in IBM PCs on power up when switches 3 and 4 on switch block 1 are set to ON. These switches must be OFF for a valid memory configuration. ILIM PRIVILEGED OPERATION EXCEPTION ERROR ILIM386 generates this error when an instruction is incompatible with the current CPU operation mode. An interaction between the application software, ILIM386, and the system BIOS can cause this error. Changing the system BIOS may solve the problem. IOCTL ERROR MESSAGE This error occurs when you change from a low speed to speed 4 using ISPEEDPC. If you receive this error you probably need newer Inboard 386/PC software, this latest software is available on the Intel BBS and on Compuserve. PARITY CHECK 2 ERROR The most common cause for this error is a result of himem.sys loading before the Inboard driver. (This the default in DOS 5.0 and Windows 3.0 installations.) To correct the problem, boot the system to a plain DOS boot disk and relocate the himem.sys command line after the INBRDPC.SYS command line. It is also possible to get a Parity Check 2 if the INBRDPC.SYS driver isn't being loaded into the Config.sys file. One Customer with a COMPAQ PORTABLE Plus and ATI Wonder Card received a Parity check 2 message on warm boot. Turning SW8 off on the ATI board solved the problem. ROM CHECK SUM ERROR If you receive this error on warm boot in an PC XT-compatible computer with a Phoenix BIOS, add the NOCACHE parameter to the INBRDPC.SYS command.
