What's new in the latest BIOS Update?

Note: Please update the BIOS on your system on your ChemBook™ 6800 to 05-30D or 05-30T ONLY IF you need to install a hard drive larger than or equal to 3 GB in capacity or if you are installing Windows 98. Otherwise it is not recommended that you upgrade the BIOS unless you have experienced specific problems that are fixed by BIOS updates. Therefore BIOS version 05-17 is available for you to download freely, while 05-30D and 05-30Ta are password protected.

How do I update the BIOS on the 6800?

To update the BIOS on the 6800 to the newest version, follow this procedure :

1. Download the BIOS update file from the 6800 FTP download page.
2. Run the downloaded executable to extract the files in the archive.
3. Boot up from a system disk. Make certain that no memory manager was loaded.
4. From the directory where the extracted files are located, type "6800".
5. The flash program will start to load the file. After it is loaded, press Enter to start.
6. Make certain that the program is not interrupted for any reason. Restart the computer when prompted.

What do I need to use Intel® Pentium® processor with MMX™ technology on the 6800?

To use the Intel® Pentium® processor with MMX™ technology, you need to acquire the following :

• A 2.8V CPU power board.
• Update BIOS to version 5-07 or above. (You can download the latest BIOS here.)
• You may also have to replace the heat sink, since the new power board is slightly larger than the original power board, and will not fit under the older heat sink.

All these are standard features on the new ChemBook™ 6800A.

Where can I find the jumper settings for the ChemBook™ 6800?

The following is the switch settings for the CPU all-in-one power board.

Why does the characters on my SVGA screen look jagged?

All ChemBook™ 6800 have SVGA screens, which displays at 800 by 600. Since the display mode for both Windows Graphics Mode and DOS mode is standard VGA, displaying at 640 by 480, you will see either one of two conditions.

• The display covers the entire screen, and the characters seem jagged, not smooth.
• The display covers only part of the screen, leaving about 1/2 inch border around the display.

To switch between the two modes, you can either press the hot-key combination Fn+F3, or enable/disable the Video Expansion Mode in the BIOS.

To display normal characters and graphics at full screen, you will need to install the device drivers and change the display resolution to 800 by 600. Follow the Installation Procedures to install the drivers.

Why was the floppy drive disabled automatically in the BIOS when I use a secondary battery?

To prevent the floppy drive from being disabled automatically in the BIOS when you insert a second battery, please update the BIOS to version 5-07 or above.

Why doesn't the 6800 BIOS detect my Toshiba hard drive?

If you have either of the following Toshiba hard disk drives, please disable LBA mode in the BIOS so that they may be automatically detected.

The model numbers are:

• HDD 2718 / MK2104MAV (2167MB)
• HDD 2912 / MK3205MAV (3053MB)

Update : This problem has been solved with BIOS version 05-20 or later. Please download the latest BIOS update here.

Why doesn't the CD-ROM appear as a device in My Computer or Device Manager in Windows 98?

Please download and update to BIOS version 05-29D or 05-29T for Dual Scan or TFT, respectively. Then, follow these steps:

1. Go to Control Panel / System / Device Manager.
2. Click on the + sign next to Hard Disk Controllers.
3. You should see Standard Dual PCI IDE Controller as one of the devices. Click on it, then click on Properties.
4. Click on the Settings tab.
5. Change Dual IDE Channel Settings from Default to Both. Then click on OK.
6. You will be asked to restart the computer. After Windows has restarted, the CD-ROM will appear as a valid device.

Why can't I enable the "Suspend to Disk" feature in BIOS when system is docked on a PCI docking station?

Since the AC power is usually turned on when system is docked on the docking station, it is illogical to shut down the power of the docking station by performing "Suspend to Disk". However, The functionality of "Suspend to DRAM" is still available when system is docked.

What kind of PCI cards can I install in the full docking station for 6800?

The following PCI cards have been tested and approved for use in the 680 full docking station.

Where is the user's manual for my 6800?

The users manual has been condensed so that it fits in the case of the Device Driver CD-ROM. The manual contains the essential, including the CPU jumper setting and BIOS settings. A more detailed users manual can be found online in the CD-ROM, as well as all device drivers and a Multimedia demonstration for the ChemBook™ 6800.

Can I use the y-shaped splitter cable with the PS/2 Port on the 6800?

The 6800 does not support the PS/2 Y-cable. If you wish to use both the external keyboard and external mouse, please use an external serial mouse, and connect the keyboard to the PS/2 port with the keyboard adapter cable.

How do I enable the Embedded Numeric Keypad?

In order for the embedded numeric keypad to function properly, you need to upgrade the BIOS to version 5-07 or later.
