Introduction:
This article has some troubleshooting tips for installing a PC/104 card on a SBC (Single Board Computer). This will apply to you if you are trying to install an Xtreme/104, Xtreme/104 Iso, Xtreme/104 Opto, ComSync/104, Xtreme/104 Radio Modem.
Instructions:
Symptoms:
You install one of our PC/104 cards using the correct jumper settings, and correct driver/software settings… BUT when you attempt to send or receive data, there is nothing happening. OR your card is not being detected during boot-up (i.e. Linux).
The most likely problem is a resource conflict in your BIOS.
Troubleshooting:
- Most BIOSes have a section where you can reserve IRQs for ISA. Be SURE to do this.
- Disable any hardware you have no need for (extra serial ports, USB, audio, LPT port, etc… )
- Some BIOSes have a section where you can reserve I/O addresses, do this.
- If it is still not working, jumper your card for a different IRQ or I/O address
- Update your BIOS to the latest version
- CTI has a utility “Port Find” that will display all the UARTS discoverable by the BIOS. If there are any resource conflicts with other hardware, this utility will bring them to your attention. Create a DOS boot disk, and add this utility to it:
