Startup/boot/loader codes
- PXE-E00: Could not find enough free base storage.
The PXE BaseCode and UNDI runtime modules are copied from FLASH memory or higher to the top of free base memory between 480 KB (78000h) and 640 KB (A0000h). The system BIOS must zero out this memory. If this memory is not filled with zeros, the reallocation code in PXE ROMs assumes that this memory is being used by the system BIOS or other boot ROMs.
- PXE-E01: PCI Vendor and Device ID do not match!
This message should never appear on a production BIOS. When the system BIOS initializes a PCI option ROM, it passes the PCI bus/device/function numbers to the AX register. If the PCI device defined in the AX register does not match the UNDI device, this error is displayed.
- PXE-E04: Error reading PCI configuration space.
This message is displayed when one of the PCI BIOS calls to read the PCI configuration space returns an error code. This shouldn't happen with a production BIOS and working hardware.
- PXE-E05: EEPROM-Prüfsummenfehler.
This message is displayed when the NIC EEPROM content has been corrupted. This can happen if the system is rebooted or powered off while the NIC EEPROM is being reprogrammed. If this message appears, the PXE ROM will not boot.
- PXE-E06: Option ROM requires DDIM support.
This message should not appear in a production BIOS. PCI Option ROMs should always be installed as DDIM Option ROMs (must be installed in upper read/write memory).
- PXE-E07: PCI BIOS calls are not supported.
This message should not appear in a production BIOS. The PCI BIOS must have PCI BIOS Services.
- PXE-E08: Unexpected API error. API: xxxxh Status: xxxxh
This message is displayed when a PXE API returns a status code that the runtime loader does not expect.
- PXE-E09: Unexpected UNDI loader error. Status: xxxxh
This message is displayed when the UNDI runtime loader returns an unexpected status code.
arp codes
- PXE-E11: ARP timeout.
The PXE ROM repeats the ARP request four times. If you do not receive a valid ARP reply, this message is displayed. This error can be caused by various network and service configuration errors. The most common ones are:
- Configure the DHCP class identifier (option 60) on the DHCP server and install the DHCP proxy on a separate computer.
- Using routers that do not respond to ARP requests.
BIOS and BIS codes
- PXE-E20: Error copying BIOS extended memory. AH == nn
