| - If the computer has the **older BIOS** such as the **003C**, the computer should ignore the part number and will attempt to boot the hard disk regardless, even with incorrect settings. However, since the settings are fixed, you can not use more than the amount of space specified in the BIOS, which is only 40 MB. To override the BIOS limitation and use more space on the disk, so you will need to manually correct the settings on boot using a drive overlay software which is installed on the hard disk. I have tested a program called Anydrive, and I believe Western Digital's EZ-Drive version 9.03W will work as well. Both programs can be found in the files section. Anydrive overrides the BIOS settings so you can use any size hard disk (or CF memory card with CF to IDE adapter) up to 504 MB. With EZ-Drive you can potentially use larger disks, but run the risk of disk file corruption above 4 GB. | - If the computer has the **older BIOS** such as the **003C**, the computer should ignore the part number and will attempt to boot the hard disk regardless, even with incorrect settings.

Programming a compatible BIOS will allow you to boot with any hard disk, and then simply install a hard disk overlay program to override the drive parameters with correct ones. The tutorial, associated ROM images and HDD overlay programs are in the [[Files and Resources]] page. | + | - If you have an EEPROM programmer, such as the Minipro TL866, you can make your own BIOS chip and replace the problematic one by using HighTreason's excellent tutorial.

| - You can also buy an XT-IDE adapter, such as the XT-CF-lite from Lo-Tech. TexElec carries these in stock in the US. This will bypass the built-in IDE controller completely and replace it with a CF card. You can then set your BIOS to "No drive". | - You can also buy an XT-IDE adapter, such as the XT-CF-lite from Lo-Tech. TexElec carries these in stock in the US.

| **A:** This could be caused by many things, but the most common issue is that the laptop lid open/close switch is just stuck in the on position. The switch, which is located under the cover, next to the floppy drive uses a rather low-quality plastic piece that latched with the screen hinge and is designed to detect when the lid is closed, and will cut the power to the display accordingly. It engages whenever the lid is closed, and since it is near the power supply, a plastic piece inside the switch may slowly deform over time and may get stuck inside the switch. The symptom you will see is a screen that will never seem to turn on when you open the lid, or will have a noisy picture, due to the switch stuck half-on. If you cannot repair the switch manually, the easiest workaround is to just disable it by removing the plastic piece entirely. This will make the screen then stay on regardless if the screen lid is open. Please see the gallery section for an image of the switch. | **A:** This could be caused by many things, but the most common issue is that the laptop lid open/close switch is just stuck in the on position.

| I have started selling replacement 003CH BIOS ROM chips for the T3200SX. If you're currently in need of upgrading your BIOS in order to install a different hard disk, you can use my BIOS chip to get around any limitations you may have with your current BIOS. The BIOS that I am selling is the the 003CH Hybrid BIOS, which is a combination of the 003C BIOS with the faster VGA BIOS of 003I. The hybrid BIOS will essentially act as an older BIOS and allow you to boot any hard disk. With this BIOS, all you need is a disk overlay program to correct the hard drive parameters. I can also program an XT-IDE enabled BIOS chip for you if you wish. Both chips are a drop-in replacement for the old BIOS chip, and should work great in any T3200SX system. | I have started selling replacement 003CH BIOS ROM chips for the T3200SX.
