5-16 Problem Solvingn Make sure you have loaded the network drivers.n Check all cable connections.n Try another port on the hub.n Make sure you have the correct type of cable between the adapter and the hub. Some hubsrequire a crossover cable while others require a straight-through cable (for more information oncrossover cabling, see your hub documentation).The Activity LED doesn’t light:n Make sure you’ve loaded the correct network drivers.n Network may be idle. Try accessing a server.The controller stopped working when an add-in adapter was installed:n Make sure the cable is connected to the port from the onboard network controller.n Make sure your PCI BIOS is current. Try the “PCI Installation Tips” below.n Make sure the other adapter supports shared interrupts. Also, make sure your operatingsystem supports shared interrupts; OS/2 does not.n Try reseating the add-in adapter.The add-in adapter stopped working without apparent cause.n Try reseating the adapter first; then try a different slot if necessary.n The network driver files may be corrupt or deleted. Delete and then reinstall the drivers.n Run the diagnostics.PCI Installation TipsSome common PCI tips are listed here.n Reserve interrupts (IRQs) and/or memory addresses specifically for ISA adapters. Thisprevents PCI cards from trying to use the same settings ISA cards are using. Use the SSU tokeep track of ISA adapter resources.n Certain drivers may require interrupts that are not shared with other PCI drivers. The SSU canbe used to adjust the interrupt numbers for PCI devices. For certain drivers, it may be necessaryto alter settings so that interrupts are not shared.BIOS User’s InformationThis section describes the various screen messages of the system BIOS. The BIOS indicates errorsby writing an error code to the PS/2-standard logging area in the Extended BIOS Data Area, andby displaying a message on the screen, which is sometimes preceded by the POST Error Code. Theerror code will also be logged to the Event Logging area.Error and Status Messages“BIOS Messages” table is an alphabetic list of error and status messages that BIOS generates and anexplanation of each message. Many of the messages refer to the built in Setup program. For moreinformation about Setup, refer to the “Configuring Your System” chapter.
