General information to read before installing
On all systems : b efore installing LAN card, go into Bios setup and set PnP OS field to NO.
• How to change LAN card configuration if needed (Advanced users only)
This is a general advisory on how to forcibly modify resources for ISA and PCI network
cards.
ISA cards:
• For ISA network adapters, start the configuration tool provided in driver
kit (See install documentation)
• Under CMOS setup, go to Advanced > PnP/PCI ISA IRQ Resource Exclu-
sion > reserve an IRQ for the adapter.
PCI cards:
• For PCI network adapters, go to CMOS setup > Advanced > PnP/PCI ISA
IRQ Resource Exclusion > reserve the IRQ for Legacy ISA.
• ISA cards can’t use IRQ9
• IRQ 9 is reported as being used by ACPI during POST. This is due to ISA’s
inability to share IRQs.
• Using a different IRQ (e.g. 5, 7, 10, and 11) will work. For this:
1 Install the NIC then power up the system.
2 Press F2 to go to CMOS setup.
3 Set PnP OS to NO and reserve IRQ 5, 7, 10, or 11 (explained in installation
section)
4 Save the configuration settings and boot to the applicable OS.
5 Follow installation steps.
Sound conflict under Win 95 on VLi8 only
• On VLi8, LAN cards cause an IRQ conflict with the embedded sound de-
vice under Win95.
• To solve the problem: Reserve IRQ 5 and sett PNP OS to no. For this:
1 Install the NIC then power up the system
