-

The information in this article applies to:


 * Microsoft Windows 95

-

SYMPTOMS
The Hewlett-Packard HP2577A 10/100VG EISA PC LAN Adapter card is not detected correctly in Windows 95. Device Manager shows a yellow exclamation point (!) in front of the device that is installed incorrectly and shows a Code 10 message. This message occurs when a device is not present or is not working properly.

CAUSE
The HP2577A 10/100VG EISA PC LAN Adapter card is preconfigured to use IRQ 3. The HP2577A cannot change the IRQ from the default setting of IRQ 3 without running the OEM configuration program, HPVGSET.

RESOLUTION
To work around this behavior, follow these steps:


 * 1) Restart the computer and press the F8 key when you see the prompt, "Starting Windows 95...." Select the Command Prompt Only option from the Startup menu that appears.
 * 2) Run the EISA configuration program for the system.
 * 3) Run the HPVGSET configuration program and select an IRQ setting other than IRQ 3, such as IRQ 5, 10, 11, or 15, for the HP2577A 10/100VG EISA PC LAN Adapter card.
 * 4) Restart the computer.

MORE INFORMATION
To change the IRQ setting, most EISA network cards require only the EISA configuration program for the system. If the IRQ setting is changed using the EISA configuration program only, the HP2577A PC LAN adapter card does not work correctly.

The HP2577A 10/100VG EISA PC LAN Adapter card is manufactured by the Hewlett-Packard Company, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
