This error generally occurs when the adapter's
EEPROM is corrupted.
Try these few steps:
1. Go to
BIOS->Settings->Reset all settings to default( look for this option inside the setup utility)
2. Go to BIOS after Resetting->Change the Boot Order as
FDD>HDD>CD/DVD.
Try to keep LAN at the bottom or exclude it from boot devices.
This should be only used if everything else fails:
3. Get a
BIOS flash update from your Motherboard Manufacturer, update the bios. This way, corrupted area will get replaced. ( Do this extremely cautiously).
Hope it Helps:
