    1. Have your serial number ready. The serial number is a six digit number located on the back of the board. It also comes up onscreen during the boot process in the GSI banner. The part number (1533-21-XX-X) is NOT the serial number.

  • Page 9 It is a 16-bit ISA-bus controller that supports Enhanced IDE hard drives & ATAPI CD-ROMs, floppy drives, and (E)IDE or floppy-interface tape drives. The Model 21 uses a 8kB Flash BIOS to make installation quick and easy. This Flash BIOS also eliminates the need for any special drivers or system CMOS support.

  • Page 12 Once you save the floppy settings, the Model 21 will “Auto-Sense” the (E)IDE drives attached. Your floppy configuration entries and the information reported to the Model 21 by the (E)IDE drives will be saved to the Model 21’s Flash BIOS. Verify, on reboot, that the GSI Banner properly reports your hard drive and floppy drive configuration, for those drives that are connected to the Model 21.
  • Page 13: Floppy Drive Installation

    When putting only one floppy drive on a cable, it is PC-standard usage to put it on the end connector, although the Model 21 will work normally with it at the center. If the system will be running Windows95, OS/2 or UNIX operating systems, see Appendix C.5. If a 2.88MB and a non- 2.88MB (floppy or tape) drive must share a cable, the 2.88MB must be declared as a GSI Type 7...

    Changing the GSI BIOS address will usually have no effect unless another controller board (e.g. SCSI or sound card) is using the same memory address and conflicting with the Model 21’s BIOS. In some cases VGA cards cause conflicts. In such cases, trying the E000 GSI BIOS address may escape this conflict.

    Choose an open slot in the computer’s motherboard and remove the rear-panel blanking plate in line with the slot, saving the screw to anchor the card in place. Gently but firmly press the GSI Model 21 into the slot, fastening it into place with the retaining screw. The case hard-drive LED wire-pair goes on J8, with the colored LED wire going to either positive (+) end pin.

    B.1.2.1 Model 21 Operating in Primary Mode (Factory Default Setting) You must declare the hard drives attached to the Model 21 in the System CMOS Setup, or else the Model 21 will not take any notice of them. Your choice of CMOS Setup Hard Drive Type may affect the proper operation of a hard drive.
  • Page 19: Gsi Model 21 Flash Bios Operation

    B.2 GSI MODEL 21 FLASH BIOS OPERATION The Model 21 remembers the hard and floppy drive configuration in Flash memory. If you install a brand new card or move a card to a different type of system, you will be asked to (re-)run GSI Setup.
  • Page 20: Gsi Model 21 Flash Bios Setup - (E)Ide Hard And Cd-Rom Drives

    If a setting in the system’s CMOS (other than Type 1) disagrees with the partition information shown (head, cylinder and sector numbers), the Model 21 will caution you that the two do not match. If a second drive is attached, you will be prompted to “Press a key to continue”, which moves on to the next drive.

    1) Run System CMOS Setup and declare the Novell hard drive as Drive Type 1 in CMOS (For Secondary Mode, do not declare a Drive Type in CMOS for drives attached to the Model 21) 2) On reboot, press <INSERT> to enter GSI Setup. Confirm that the GSI Hard Drive Setup screen for the Novell hard drive has the proper information in it.

    3.)Run Novell’s Surface Test on each Novell Partition. To use the Model 21 with Novell 3.xx, you must have NetWare 3.11 or later. You can call the Novell BBS (or contact your Novell office) to get the current version of Novell’s IDE.DSK. Make sure the version of that driver is June of 1994 or later.

    If, due to this limitation, you must put a normally GSI BIOS Type 5 (or Type 6) 2.88MB drive on the REG cable, remember to declare it as a Type 7 in GSI Floppy Setup. Consequently, plan your floppy letter assignments and cable-connect the drives accordingly:...

    Note: n in the TEAC Model #s is a bezel color digit. Using two 2.88MB floppy drives which have different GSI BIOS Drive Types is not recom- mended. If you must do this, you may need to assign both drives the GSI BIOS Drive Type 7 during GSI setup sequence.

    The Master mode can be used for two situations. If you have only one hard drive (or other IDE device) attached to the Model 21, it can be set as Master or Standalone. If you are running two drives on the Model 21, one should be set as Master and the other as Slave.
  • Page 30: System Cmos Setting For (E)Ide Hard Drives

    E.1.3 System CMOS Setting for (E)IDE HARD Drives When the Model 21 is operating in Primary Mode, hard drives must be declared in CMOS. Do not declare IDE Tape and CD-ROM drives in the system CMOS. Also, when operating in Secondary Mode, you do not declare hard drives in the system CMOS.
  • Page 31: E)Ide Hard Drives Not Formatted To Full Capacity

    In the above case where the full capacity of the drive is not being used, the Model 21 will use the partition information placed on the drive by the old controller. Data saving cannot be guaranteed but the user may want to take advantage of this capability.

    F.1 INTEGRATING FLOPPY-INTERFACE TAPE UNITS The GSI Model 21 can control one QIC-3010, QIC-80 or QIC-40 tape unit — along with up to four floppy drives. In fact, the Model 21 operates the QIC-80 & QIC-3010 tape units at their faster, double-speed, transfer rate (1Mbit/sec), saving you the cost of a separate high speed tape-only controller.
