Pxe configuration utility updating

If you are installing the adapter in an x86 system, and you plan to use Preboot Execution Environment (PXE) functionality, you might need to update the Converged Network Adapter PXE under the BIOS and UEFI environments.

The documentation does not say what value (hexadecimal, string or whatever) must be included within the "-MODE=value" option in command line to be properly written to EEPROM.This should not happen to such important things and should be well documented with example values, even if NICs and their chipsets EEPROM mappings and registers has still been evolving and differ between the evolving process.Because I am kind of intellectually curious person, I decided during my personal usage of Boot Util to send via this "-MODE" option some random value to test what will happen and surprisingly the provided value within command line was accepted by flashing utility and EEPROM of my card was updated.I did not know what EEPROM register was changed and I thought it was something important that will have a significant impact on the funcionality of my card and I had to look into document of Intel 82559ER Fast Ethernet describing EEPROM map and contents for reference to get acquainted with the EEPROM registers and their detailed working behind the scenes (even if I own SB82258B chipset as I was not able to find EEPROM mapping based on this chipset).By using some ways of dumping EEPROM content of my NIC I discovered that the "-MODE" option allows you to change both -STE(D) and -TLE(D) into enabled state by sending just one 16-bit word through this very "-MODE" option when providing it in hexadecimal notation like 0x4000 form (4000 would do the same effect and this is also the value set when using -DEFCFG (Default config - this brings everything back to Default in PXE touching all other PXE settings too), and is accepted too as long as the value is between 0000-FFFF.(Please note, however that if you specify value (prior to your knowledge of knowing what this option does) like FFFF and use later the following command: BOOTUTIL -STD -TLD -NIC 1 than that will change the value "FFFF to "FFFC" in WORD 31 of EEPROM which instructs to disable Setup Menu and remove Initial Title Message from appearing on POST but after you rebooted your PC you are surprised seeing Initial Title Message and you can still reach Setup Menu by pressing CTRL S keys.That is because value 4000 will be set again automatically, since "FFFF" value passed via "-MODE" option was initially accepted by Boot Util but not accepted by chip configuration and messed up the configuration you wanted to set in the first place and you need to rerun Boot Util to reconfigure Setup menu and Initial Title Message thingy, again.) To sum that up.The WORD 31 register in EEPROM and the two mentioned options are only changed while sending hexadecimal value through the described "-MODE" option.The other options that are part of PXE Configuration like -MSE -SETWAITTIME=x are NOT changed when passing the "-MODE" option to Boot Util.A part of documentation concerning PXE Boot Configuration at the bottom of this post is revised by me to describe (hopefully) better what this "-MODE" option really does for actually 82558B chipset based cards and Compaq/HP NC3121 when it is flashed with default Boot IMG.FLB (included in Boot Util) and -up=pxe option to change a PXE feature from LANDesk Service Agent v0.99b (1997) to that of Intel Boot Agent v4.2.04 along with PXE 2.1 (2011). -TITLEENABLE OR -TLE Enables Initial Title Message.
