How do I update the BIOS on the 2600?

To update the BIOS on the 2600 to the newest version, follow this procedure :

1. Download the BIOS update file from the 2600 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 "flash x.x", where x.x is the file name of the BIOS file.

5. The flash program will start to load the file. After it is loaded, press B to begin.

6. Make certain that the program is not interrupted for any reason. Restart the computer when prompted.

Where can I find the BIOS version number on my system?

You can find the correct BIOS version number only by pressing F2 upon boot up to enter SCU. The BIOS version is the number displayed on the first page of the SCU Setup. The System BIOS version which is displayed outside the SCU BIOS Setup will always show version 1.01 regardless of the BIOS update revision.

Why does the characters on my SVGA screen look jagged?

All ChemBook™ 2600 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 have to enable / disable the VGA Expansion Mode in the BIOS/Advanced menu.

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 can't I set up the Audio Driver and PCMCIA drivers in Windows 3.x?

If you encounter problems using the different built-in devices on the ChemBook™ 2600 in Windows 3.x, please disable the Plug and Play O/S setting in the BIOS / Advanced menu.

How do I set up the 2600 to support a second hard disk?

To use 2 or 3 hard drives simultaneously on the 2600, you must be aware of the following:

• You must purchase an optional 2nd Hard Drive Case for each hard drive in addition to the original hard drive.

• The Hard drive in the Left Smart Bay has to be set to Slave via a jumper on the hard drive. It will be the Secondary Slave IDE Device in the BIOS.

• The Hard drive in the Right Smart Bay has to be set to Master. It will be the Secondary Master IDE device in the BIOS.

Why does MIDISK show me that it is allocating more than the normal 18 cylinders?

Why don't the PCMCIA slots work under Windows 95 or Windows 95 a?

Since the 2600 has 2 Cardbus Slots, and Cardbus slots requires Windows 95B for support, you will not be able to use the PCMCIA slots if you have any earlier version, i.e., Windows 95 or Windows 95a (with Service Pack 1). You can only enable the Cardbus PCMCIA slots in Windows 95 B (OSR2).

Why doesn't Windows 95 B (OSR2) boot up with a Cardbus Ethernet Card inserted?

If you are experiencing trouble booting Windows 95B with a Cardbus Ethernet Card inserted in the PCMCIA slot, please download the Cardwizard PCMCIA driver for Windows 95 from the 2600 FTP Download Page.
