Advanced Installation Guide for BocaRam/AT Plus (BRAT80/BRAT90) Before installing the BocaRam/AT Plus: Be sure the board is populated with at least 2MB RAM. Populate the board starting with Bank 0 and Bank 1 See manual for illustrations. Installation Guide: Insert board in a 16-bit slot. Power the machine on with a "plain vanilla" boot diskette. (one with no CONFIG.SYS or AUTOEXEC.BAT file) After boot is complete, insert the BocaRam/AT Plus installation disk. Type ADVINST at the A:\> prompt Program Guide: Screen 1: Introduction, press any key to continue. Screen 2: This screen should tell how much memory you have installed on the BocaRam/AT Plus board. If the amount is correct, press "Y" for yes. If the installation program does not recognize the amount of memory on the Boca memory board then you may have a problem. To continue, enter the amount of RAM you have installed and then press ESC to move to the next screen. Remember, RAM must be installed in 2MB increments. Screen 3: CPU and Bus speeds. Both of these questions should be answered by the program. If they are correct, then answer YES to confirm each question. If the program is incorrect or asking for the proper speeds, consult your computer's documentation for the proper answers. Normally, the Bus speed is 1/2 to 1/3 the speed of the CPU clock speed. i.e. 286-12Mhz, CPU 12Mhz, BUS 6 or 8Mhz. If in doubt choose 8Mhz as your Bus speed. Screen 4: Memory Allocation Menu. For this task you will use the arrow keys and the plus (+) and Minus (-) keys to allocate memory that fits your needs. This screen only shows the memory on the BocaRAM/AT Plus board. It will not show existing memory on the motherboard. If you have only 512K memory on the motherboard, you must back-fill conventional memory. Increase the conventional memory option to 128K, which gives you 640K total. Then allocate the rest of the memory to Extended and/or Expanded memory based on your present needs. To set the Extended Memory Start, accept the default or see document on "Selecting the Proper Start Address". Extended memory stop is set automatically. Screen 5: RAM speed and wait states. The RAM Access Speed should match the speed of the RAM if it is 80ns to 120ns, 100ns is the default. If the RAM is faster than 80ns (or a lower number) then the RAM Access Speed should be set to 80ns. The board is designed to handle RAM that is 80ns to 120ns in speed. If the BUS Speed in Screen 3 was 4Mhz to 8Mhz the Total Wait States can be set to Zero. If the BUS Speed is 10Mhz or higher then the Total Wait State should be at least 1. Set it to 2 total wait states if the BUS is 12Mhz or higher. Press ESC when complete. If the RAM access speed is 0ns then you may have a problem. Set the Access speed to the proper setting. Setting the total wait state to a higher number can help the board overcome bus noise and interference. Screen 6: PARITY? Always say no to this question. Parity is only used for older RAM chips that require that sort of testing. The basic installation program sets parity to NO as a default. Extended Memory Screen 7a: Update CMOS. If you configure the BocaRam/AT Plus for all Extended Memory, this would be the last screen you'll see in the installation process. You say yes to updating the CMOS configuration. This will update your computers memory setup and reboot. During the Boot process the machine will count the extra installed memory. If you have installed Expanded Memory, you will be asked to choose the proper addresses that the manager will use. Expanded Memory Screen 7b: I/O Address selection. The default is 268h. Unless this is a known conflict with another device in your machine, accept it, as is. Screen 8: Page Frame Address: This board provides up to 128K to address your page frame. The minimum requirement is 64K. That translates to four 16K pages in a row. The addresses that are available are C000, C400, C800, CC00, D000, D400, D800, DC00. You will need to choose at least four of the pages the are continuous. NOTE: If you have VGA installed, C000 and C400 will not be available for use by the memory board. Network boards also use an address in this area and should be inspected before configuring this board as Expanded Memory. Follow the instructions on the screen to select the page frames you would like to use for the memory specification. Then press ESC to continue. Screen 9: Update CONFIG.SYS file: Choose yes to updating the file. If you have already done this it will not damage any files to do it again. After the installation program is complete, you may want to inspect the CONFIG.SYS file to ensure that the appropriate lines were added. Screen 10: Update CMOS. See screen 7a above. Installation is Complete. If the program did not follow this guide smoothly then you may be facing one the many pitfalls in memory upgrading. For example, if the Advanced Installation Program does not recognize how much memory is on the board, you may have the RAM installed improperly or the RAM may be defective. If the installation runs smoothly and there is a problem with the application your are running, then run the BRPTEST program on the Boca diskette. The RAM chips or the address space on the motherboard may be defective. Remember to always boot with a plain vanilla DOS diskette (one with no AUTOEXEC.BAT or CONFIG.SYS) when working with the board. Severe Error 002: This is a message that informs of an inability to program the EEPROM on the BocaRam/AT Plus board. Either the 300h address is in conflict with another board or the jumper to enable/disable the EEPROM is set improperly. If problems persist beyond the issues described in this document, call the Technical Support Department. The phone number is found in the product manual.
