- BIOS Upgrade utilities
- 2. Information on the usage of the 3D Blaster PCI
- Control Panel for DOS (VTOOL.EXE)
-
-
- 1. Information on the 3D Blaster PCI Control Panel BIOS Upgrade utilities
- ======================================================================
-
- The 3D Blaster PCI BIOS Upgrade utilities consist of the following
- files:
-
- * RESET.COM
- * AUTOEXEC.BAT
- * 3DB103P3.EXE
-
- How to use 3DB103P3.EXE
- =======================
-
- (A) This program is executable in native DOS (MS-DOS 6.2x) or Windows
- 95 DOS box. However, it is *highly recommended* to run the program
- in native DOS.
-
- (B) IMPORTANT: For safety reasons, it is recommended that you prepare a
- Recovery Disk before flashing your BIOS. You can do this by copying
- the following 3 files to a *bootable* floppy disk:
-
- AUTOEXEC.BAT
- 3DB103P3.EXE
- RESET.COM
-
- (C) Before flashing, make sure you set the CMOS settings of your system
- to allow booting from a floppy disk.
-
- (D) Simply run the program 3DB103P3.EXE in DOS prompt. You will be
- asked to "press any key to continue".
-
- (E) The programming process takes about 20 seconds (including
- verification time) to complete. This process should NOT be
- interrupted. Failing to observe this may result in unexpected
- (and undesirable) consequences.
-
- (F) When asked to restart computer, reset the system using your PC's
- Reset button.
-
- (G) The system should now boot up with the updated 3D Blaster PCI BIOS.
-
-
- Troubleshooting BIOS Upgrade Utility Issues:
- ===========================================
-
- IMPORTANT NOTE: If you own an AST Advantage or Bravo machine,
- specifically if the motherboard utilises a set of 4
- SIS chipsets, the 3D Blaster PCI might not be
- correctly reflashed when executed on this machine.
- If you find that your PC system hangs during the
- reflashing process, follow the Trouble-Shooting tips
- mentioned below.
-
- If you are still unable to complete the reflashing
- task, try to borrow/obtain a non-AST machine and
- follow the steps listed above to flash the 3D Blaster
- PCI BIOS on that machine. Once this has been
- successfully completed, replace the newly flashed
- 3D Blaster PCI card into your AST system, and it
- should now work without any problems.
-
- * If you do not see any display upon reboot of PC system:
-
- In such a case, place the Recovery Disk in your drive. Reset your
- PC system. You will hear two beeps, and after a while you should
- see the floppy disk drive light turn on. The Recovery Disk will
- attempt to reprogram your 3D Blaster PCI BIOS at this stage. On
- success, a cold reboot will automatically be done.
-
- At this point, you should remove the diskette from the drive. Your
- system should now work properly.
-
-
- * In the case when the 3D Blaster PCI BIOS is still not programmed
- properly for whatever reason:
-
- You may try to reprogram it with the use of another PCI-based VGA
- card.
-
- Insert a second PCI VGA card into the 1st PCI slot and the 3D
- Blaster PCI into the second PCI slot. Connect the VGA card output
- to a monitor, boot up and check if the monitor displays anything.
- If it doesn't, swap the slot positions of the VGA card and 3D
- Blaster PCI, or move the 2 cards among the different PCI slots,
- and try booting up again. When the systems boots up successfully
- with the VGA card, you can then program the 3D Blaster PCI BIOS
- as described above, beginning from Step (A).
-
-
- 2. Information on the 3D Blaster PCI Control Panel for DOS (VTOOL.EXE)
- ===================================================================
-
- VTOOL is a DOS utility for the 3D Blaster PCI that allows you to
-
- * check the BIOS version of your 3D Blaster PCI
- * toggle various settings of VGA Mode 13 on the 3D Blaster PCI
- * toggle various monitor refresh rates supported by the 3D
- Blaster PCI
- * reports and tunes your 3D Blaster PCI for best performance
- * change your PCI Bus Master Latency settings
-
- VTOOL can be executed from the MS-DOS prompt using the following
- syntax:
-
- usage: VTOOL [/B] [/I:<IRQ>] [/M:<refresh>] [/S:<VGA speed>] [/V]
-
- where [] indicates optional switches.
-
- Any number of switches can be specified at one time, and they can be
- in any order. However, VTOOL must be run either in native DOS or in
- a *full-screen* DOS Box. It will not work properly when run under
- windowed DOS Box. All VTOOL settings are only valid for the current
- session and will be reset upon the next reboot.
-
- VTOOL Switches
- --------------
-
- (A) Diagnostics (option '/V')
-
- usage: VTOOL /V:<1 or 2>
-
- e.g. "VTOOL /V:1" for basic diagnostics
- "VTOOL /V:2" for detailed diagnostics
-
- This switch performs some basic diagnostics on your 3D Blaster
- PCI card. It reports the following information:
-
- a. the version of your 3D Blaster PCI's Video BIOS.
- b. the current VESA horizontal refresh rate.
- c. the current VGA Mode 13 toggle state.
- d. the IRQ currently assigned to the card.
- e. whether bus-mastering is disabled on the card.
-
- If option '/V:2' is specified, additional diagnostics are
- performed:
-
- a. If bus-mastering is enabled, it will report the FIFO and
- bus-mastering performance of your 3D Blaster PCI.
- b. it will also suggest the best PCI Latency value to set to
- obtain the best best-mastering performance. You can use this
- suggested value with the '/L' option (see section (E)).
-
- (B) VGA Mode 13 (320x200x256 colors) toggle (option '/S')
-
- usage: VTOOL /S:<0, 1 or 2>
-
- e.g. "VTOOL /S:1" for selecting normal VGA mode 13
-
- /S:0 gives the most compatible VGA mode 13. It gives the slowest
- 320x200x256 color speed, but is compatible with all applications.
-
- /S:1 is the power-up default. It gives faster 320x200x256 color speed,
- and is compatible with most applications, including those using
- 320x240x256 or other variants.
-
- /S:2 maps VGA mode 13 (320x200x256 colors) to its VESA equivalent.
- This gives the fastest mode 13 speed, but is not compatible
- with all applications. Applications using 320x240x256 or other
- variants or using special VGA features will not work.
-
- (C) Assign IRQ (option '/I')
-
- usage: VTOOL /I:<IRQ number in hex>
-
- e.g. "VTOOL /I:0C" will force IRQ 0Ch to be assigned to the 3D
- Blaster PCI card
-
- This option should not be used unless your system does not allocate
- an IRQ to the 3D Blaster PCI card. It forces the 3D Blaster PCI to
- use the specified IRQ. Make sure that the IRQ you select is not in
- use by any other card in your PC system.
-
- (D) Enable bus-mastering (option '/B')
-
- usage: VTOOL /B
-
- This option should be used with care. On most systems, the system
- BIOS enables the bus-mastering feature on the 3D Blaster PCI by
- default, so you do not need to use this command. On a few systems
- however, the system BIOS may disable the bus-mastering feature.
- If you are sure your system is capable of supporting PCI bus-
- mastering, you can use this option to force it to be used.
-
- (E) PCI Bus Master Latency (option '/L')
-
- usage: VTOOL /L:<PCI Latency value in CLKs - 0 to 255>
-
- e.g. "VTOOL /L:32" will set your 3D Blaster's PCI Bus Master
- Latency value to 32 clocks (1 microsecond
- on a 33MHz PCI Bus)
-
- On most systems, the system BIOS will allow you to set the PCI
- Latency value, so use that instead. On those systems which do not
- have such a setting, or if you have more than one PCI card in your
- system, you can use this option to set the PCI Latency value for
- your 3D Blaster PCI. See section (A) Diagnostics (option '/V:2')
- for more details.
-
- (F) Screen centering (option '/A')
-
- usage: VTOOL /A
-
- With 3D Blaster PCI BIOS v1.00.73.2 and above, you can individually
- center each VESA video mode. Follow the on-screen prompts to select
- the video mode to center, and use the cursor keys to move the image
- on screen to its desired position. Note that you should *first* set
- your desired monitor refresh rate (with '/M') before centering, as
- the centering options only take effect for the current monitor
- refresh rate. If you change your refresh rate settings, you will
- have to re-center all your video modes again.
-
- (G) VESA Refresh Rates (option '/M')
-
- On power-up, the 3D Blaster PCI defaults to a class 1 monitor's
- (14" SVGA) refresh rates. This can be changed by using the control
- panel.
-
- usage: VTOOL /M:<monitor's max horizontal freq>
-
- e.g. "VTOOL /M:57" for class 9 57KHz monitor
-
- The refresh rates supported for each class of monitor at different
- resolution is listed below:
-
- ** Refresh support table **
-
- Class # Max Horizontal Vertical refresh rate (Hz) at resolution
- frequency 640x480 800x600 1024x768 1280x1024
- (KHz)
-
- 0 31.5 (VGA monitors) 60 - - -
- *1 35.1 (14" SVGA monitors) 60 56 - -
- 2 37.5 75 56 - -
- 3 37.8 75 60 - -
- 4 43.2 85 60 - -
- 5 46.8 85 75 - -
- 6 48.3 85 75 60 -
