The following is a comprehensive list of PXE errors and their meaning.
Init/Boot/Loader Codes
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.
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.
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.
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.
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).
This message should not be seen in a production BIOS. PCI BIOS must have PCI BIOS services.
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
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:
BIOS and BIS Codes
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).
This message is displayed if the BIS image in extended memory has been corrupted.
The downloaded image and credential do not match the client key.
BIS could not be initialized. No more data is available.
BIS could not be shutdown. No more data is available.
Could not determine if BIS is enabled/disabled.
Could not release BIS allocated memory.
Required BIS credential type information could not be determined.
BIS entry structure in the SM BIOS table is invalid.
TFTP/MTFTP Codes
TFTP open request was not acknowledged. Verify that the TFTP service is running.
Next TFTP data packet was not received.
A TFTP error packet was received from the TFTP server.
A hardware error occurred when trying to send the TFTP open packet out.
A hardware error occurred when trying to send a TFTP acknowledge packet out.
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.
The request file was found on the TFTP server. The TFTP service does not have enough access rights to open/read the file.
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
The client did not receive any valid DHCP, BOOTP, or proxyDHCP offers.
The client did not receive any valid DHCP or BOOTP offers. The client did receive at least one valid proxyDHCP offer.
The client received at least one valid DHCP/BOOTP offer but does not have a boot filename to download.
The client issued a proxyDHCP request to the DHCP server on port 4011 but did not receive a reply.
UNDI Codes
An API being used by the BaseCode is not implemented in the UNDI ROM.
Most likely the cable is not plugged in or connected. Could be a bad cable, NIC, or connection.
An error occurred while trying to initialize the NIC hardware. Try another NIC.
An error occurred while trying to initialize the PHY hardware. Try another NIC.
An error occurred while reading the NIC configuration data. Try another NIC.
An error occurred while reading the NIC initialization data. Try another NIC.
The MAC address stored in this NIC is invalid. Try another NIC.
The EEPROM checksum is invalid. The contents of the EEPROM have been corrupted. Try another NIC.
The interrupt hardware could not be configured. Try another NIC.
Bootstrap and Discovery Codes
PXE tags were detected, but the boot menu and/or boot prompt tags were not found/valid.
Multicast discovery is enabled but the multicast discovery address tag is missing.
Multicast and broadcast discovery are both disabled, or use server list is enabled, and the server list tag was not found/valid.
A valid boot server reply was not received by the client.
The NBP is larger than the amount of free base memory.
This message is displayed when the client did not receive any security information from the boot server and BIS is enabled on the client.
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
The !PXE structure is missing or has been corrupted.
The PXENV+ structure is missing or has been corrupted.
PXE discovery tags in the cached packets are not valid.
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.
The size of the RAMdisk image is larger that the available extended memory.
The bootstrap program was expecting a DOS diskette image. The first 512 bytes of the downloaded image did not contain a DOS boot signature.
The cached discovery reply packet did not contain a PXE boot-item tag (PXE option 71).
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.
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
User pressed ESC during DHCP/Discovery/TFTP.
BaseCode/UNDI Loader Codes
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.
The BaseCode ROM ID structure is invalid. The BaseCode ROM image has probably been corrupted.
The BaseCode loader module could not locate the UNDI ROM ID structure.
The UNDI ROM image has probably been corrupted.
The UNDI ROM image has probably been corrupted.
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:
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:
