Resolution
Init/Boot/Loader Codes:
PXE-E00: Could not find enough free base memory
PXE BaseCode and UNDI runtime modules are copied from FLASH or upper memory into the top of free base memory between 480K (78000h) and 640K (A0000h). This memory must be zero-filled by the system BIOS. If this memory is not zero-filled, the relocation code in the PXE ROMs will assume that this memory is being used by the system BIOS or other boot ROMs.
PXE-E01: PCI Vendor and Device IDs do not match
This message should never be seen in a production BIOS. When the system BIOS initializes a PCI option ROM, it is supposed to pass the PCI bus/device/function numbers in 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 if any of the PCI BIOS calls made to read the PCI configuration space return an error code. This should not happen with a production BIOS and properly operating hardware.
PXE-E05: EEPROM checksum error
This message is displayed if the NIC EEPROM contents have been corrupted. This can happen if the system is reset or powered down when the NIC EEPROM is being reprogrammed. If this message is displayed the PXE ROM will not boot.
PXE-E06: Option ROM requires DDIM support
This message should not be seen in a production BIOS. PCI option ROMs must always be installed as DDIM option ROMs (they must be installed into read/write upper memory).
PXE-E07: PCI BIOS calls not supported
This message should not be seen in a production BIOS. PCI BIOS must have PCI BIOS services.
PXE-E08: Unexpected API error. API: xxxxh Status: xxxxh
This message is displayed if a PXE API returns a status code that is not expected by the runtime loader.
This message is displayed if the UNDI runtime loader returns an unexpected status code.
ARP Codes:
PXE-E11: ARP timeout
The PXE ROM will retry the ARP request four times. If it does not get any valid ARP replies, this message is displayed. This error can be caused by a number of network and service configuration errors. The most common are:
Setting the DHCP Class Identifier (option 60) on the DHCP server and installing the proxyDHCP on a separate machine
Using routers that do not respond to ARP requests
BIOS and BIS Codes:
PXE-E20: BIOS extended memory copy error. AH == nn
This message is displayed if the BIOS extended memory copy service returns an error. This should not happen on a production BIOS. The variable "nn" is the BIOS error code returned by the BIOS extended memory copy service (Int 15h, AH = 87h).
PXE-E21: BIS integrity check failed
This message is displayed if the BIS image in extended memory has been corrupted.
PXE-E22: BIS image/credential validation failed
The downloaded image and credential do not match the client key.
PXE-E23: BIS initialization failed
BIS could not be initialized. No more data is available.
PXE-E24: BIS shutdown failed
BIS could not be shutdown. No more data is available.
PXE-E25: BIS get boot object authorization check flag failed
Could not determine if BIS is enabled/disabled.
PXE-E26: BIS free memory failed
Could not release BIS allocated memory.
PXE-E27: BIS get signature information failed
Required BIS credential type information could not be determined.
PXE-E28: BIS bad entry structure checksum
BIS entry structure in the SM BIOS table is invalid.
TFTP/MTFTP Codes:
PXE-E32: TFTP open timeout
TFTP open request was not acknowledged. Verify that the TFTP service is running.
PXE-E35: TFTP read timeout
Next TFTP data packet was not received.
PXE-E36: Error received from TFTP server
A TFTP error packet was received from the TFTP server.
PXE-E38: TFTP cannot open connection
A hardware error occurred when trying to send the TFTP open packet out.
PXE-E39: TFTP cannot read from connection
A hardware error occurred when trying to send a TFTP acknowledge packet out.
PXE-E3A: TFTP too many packages
This message can mean one of two things:
PXE-E3B: TFTP error - File not found.
The requested file was not found on the TFTP server.
PXE-E3C: TFTP error. Access violation
The request file was found on the TFTP server. The TFTP service does not have enough access rights to open/read the file.
PXE-E3F: TFTP packet size is invalid
The TFTP packet received is larger than 1456 bytes. Using TFTP, you are trying to download a file that is larger than the allocated buffer. Using MTFTP, you started downloading a file as a slave client, and the file increased in size when you became the master client.
BOOTP/DHCP Codes:
PXE-E51: No DHCP or proxyDHCP offers were received
The client did not receive any valid DHCP, BOOTP, or proxyDHCP offers.
PXE-E52: proxyDHCP offers were received. No DHCP offers were received
The client did not receive any valid DHCP or BOOTP offers. The client did receive at least one valid proxyDHCP offer.
PXE-E53: No boot filename received
The client received at least one valid DHCP/BOOTP offer but does not have a boot filename to download.
PXE-E55: proxyDHCP service did not reply to request on port 4011
The client issued a proxyDHCP request to the DHCP server on port 4011 but did not receive a reply.
UNDI Codes:
PXE-E60: Invalid UNDI API function number
An API being used by the BaseCode is not implemented in the UNDI ROM.
PXE-E61: Media test failed, check cable
Most likely the cable is not plugged in or connected. Could be a bad cable, NIC, or connection.
PXE-E63: Error while initializing the NIC
An error occurred while trying to initialize the NIC hardware. Try another NIC.
PXE-E64: Error while initializing the PHY
An error occurred while trying to initialize the PHY hardware. Try another NIC.
PXE-E65: Error while reading the configuration data
An error occurred while reading the NIC configuration data. Try another NIC.
PXE-E66: Error while reading the initialization data
An error occurred while reading the NIC initialization data. Try another NIC.
PXE-E67: Invalid MAC address
The MAC address stored in this NIC is invalid. Try another NIC.
PXE-E68: Invalid EEPROM checksum
The EEPROM checksum is invalid. The contents of the EEPROM have been corrupted. Try another NIC.
PXE-E69: Error while setting interrupt
The interrupt hardware could not be configured. Try another NIC.
Bootstrap and Discovery Codes:
PXE-E74: Bad or missing PXE menu and/or prompt information
PXE tags were detected, but the boot menu and/or boot prompt tags were not found/valid.
PXE-E76: Bad or missing multicast discovery address
Multicast discovery is enabled but the multicast discovery address tag is missing.
PXE-E77: Bad or missing discovery server list
Multicast and broadcast discovery are both disabled, or use server list is enabled, and the server list tag was not found/valid.
PXE-E78: Could not locate boot server
A valid boot server reply was not received by the client.
PXE-E79: NBP is too big to fit in free base memory
The NBP is larger than the amount of free base memory.
PXE-E7A: Client could not locate a secure server
This message is displayed when the client did not receive any security information from the boot server and BIS is enabled on the client.
PXE-E7B: Missing MTFTP server IP address
This message is displayed when the ROM did not receive any PXE discovery tags or proxyDHCP offers and the DHCP SIADDR field is set to 0.0.0.0.
APITest.0 and DOSUNDI.0 Codes:
PXE-E81: PXE structure is invalid
The PXE structure is missing or has been corrupted.
PXE-E82: PXENV+ structure is invalid
The PXENV+ structure is missing or has been corrupted.
PXE-E83: Invalid DHCP option format
PXE discovery tags in the cached packets are not valid.
PXE-E84: Could not get pointer to original packet storage
The PXE ROM being used did not return pointers to its local cached packet storage. The API test bootstrap program will not work with this boot ROM.
PXE-E85: Not enough extended memory
The size of the RAMdisk image is larger that the available extended memory.
PXE-E86: ENV RAMdisk image corrupted
The bootstrap program was expecting a DOS diskette image. The first 512 bytes of the downloaded image did not contain a DOS boot signature.
PXE-E87: Could not find selected boot item
The cached discovery reply packet did not contain a PXE boot-item tag (PXE option 71).
PXE-E88: Could not locate boot server
The bootserver did not reply to the RAMdisk image discovery request. The RAMdisk image is not on the bootserver, or the bootserver service is not running.
PXE-E89: Could not download boot image
The RAMdisk image could not be downloaded. The RAMdisk image is not on the bootserver, or the TFTP service on the bootserver is not running.
Miscellaneous Codes:
PXE-EA0: Network boot canceled by keystroke
User pressed ESC during DHCP/Discovery/TFTP.
BaseCode/UNDI Loader Codes:
PXE-EC1: BaseCode ROM ID structure was not found
UNDI boot module could not find the BaseCode ROM ID structure. If there is a BaseCode ROM image in the system, it has probably been corrupted.
PXE-EC3: BaseCode ROM ID structure is invalid
The BaseCode ROM ID structure is invalid. The BaseCode ROM image has probably been corrupted.
PXE-EC4: UNDI ROM ID structure was not found
The BaseCode loader module could not locate the UNDI ROM ID structure.
PXE-EC5: UNDI ROM ID structure is invalid
The UNDI ROM image has probably been corrupted.
PXE-EC6: UNDI driver image is invalid
The UNDI ROM image has probably been corrupted.
PXE-EC8: PXE structure was not found in UNDI driver code segment
The UNDI ROM image has probably been corrupted or has not been initialized by the BIOS. This error is most often caused by one of three things:
A NIC image was programmed into a BIOS when a .LOM image should have been used.
The memory allocated by the POST Memory Manager (PMM) during PXE option ROM initialization has been corrupted or erased before PXE option ROM boot.
The UNDI_Loader structure was not properly initialized during option ROM initialization.
PXE-EC9: PXENV+ structure was not found in UNDI driver code segment
The UNDI ROM image has probably been corrupted or has not been initialized by the BIOS. This error is most often caused by one of three things:
A NIC image was programmed into a BIOS when a .LOM image should have been used.
The memory allocated by the POST Memory Manager (PMM) during PXE option ROM initialization has been corrupted or erased before PXE option ROM boot.
The UNDI_Loader structure was not properly initialized during option ROM initialization.
