After you install Windows 98, Device Manager may display an exclamation point in a yellow circle next to the PC Card (PCMCIA) network adapter, with a status of "Error Code 10" in the adapter's properties.


This behavior can occur on a Digital HiNote Ultra II laptop when the PC Card network adapter uses memory that the computer's Basic Input/Output System (BIOS) has reserved.

Windows 98 determines a free range of memory and then assigns that range to the network adapter for use. The network adapter driver may not be able to use the assigned range if it is reserved by the BIOS.


To work around this issue, you may be able to exclude the memory range that is being reserved by the BIOS. To do this, follow these steps:

  1. Click Start, point to Settings, and then click Control Panel.
  2. Double-click System.
  3. On the Device Manager tab, double-click Computer.
  4. Click the Reserve Resources tab, and then click Memory.
  5. Click Add, type CA000 in the Start Value box, and then type CB000 in the End Value box.
  6. Click OK, and then click OK.
  7. Click the PC Card network adapter, and then click Remove.
  8. Click OK, and then click Close.
  9. Restart your computer.
