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.

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.
Model 21 (usually Standalone or Master). If there are two (E)IDE devices connected to the GSI Model 21, you must set one as the Master and the other as the Slave.

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.
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.
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.
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.
E pages of memory) in 16kB, 32kB, or 64kB blocks. Any of these block sizes will totally contain the Model 21’s 8kB BIOS. Note your GSI BIOS Start Address as shown in your GSI Bootup Banner and request shadowing, in your Advanced CMOS System Setup, as follows:...
1.44MB drive. Try excluding the memory region of the GSI BIOS from the memory manager’s optimization process. Example: In the CONFIG.SYS file add the exclude option for a Model 21 whose BIOS is at the CC00 address: Memory Manager Exclusion Statement DOS’...
C.2 USING MEMORY MANAGER SOFTWARE (CONT.) If you are using a different GSI BIOS address (confirm BIOS address from GSI Banner), the following table shows which regions should be excluded accordingly: GSI BIOS Address Exclude Region GSI BIOS Address Exclude Region...
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.
Sony Model MP-F40W-15 D.4 FLOPPY DRIVE MIX POSSIBILITIES The Model 21 floppy interface can accommodate any mix of up to four 5.25"/3.5" floppy drives. What restrictions there are relate mostly to 2.88MB drives. If you have a smart 2.88MB GSI BIOS...
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.
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.
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.

These are absolutely standard usages for PCs and should pose no incompatibility issues. F.7 PRODUCT SPECIFICATIONS The GSI Model 21 Intelligent IDE Accelerator Board uses the Part #: 1533-21-xx-x, where xx-x is the board revision number. It is distributed two ways: in bulk (where GSI supplies the board, manual and registration card) and in VAR packs (1533-21-Vx-x) where GSI supplies one floppy disk drive cable, one IDE hard drive cable, manual and product registration card.
The two channel VESA Extender cannot add a second channel to the GSI Model 21, your system must have two GSI ISA channels already (i.e. a GSI Model 21 in primary mode and the GSI Model 18 in secondary mode).
