Network Controller in Toshiba® Tecra A11
Network controller is software that manages the communication between main and stands alone computers. It resides in the communications controller processor on the server and manages requests from workstations. In a LAN, it is referred as network operating system (NOS). The process is implemented via electronic circuit on the Ethernet. This communication process is applicable on small-scale networks like LAN and large-scale networks like IP.

What is network controller?
Network controller is an interface that allows and manages robust communication between workstations and servers. The hardware device that handles the network controller is called Network Interface Card (NIC) and contains ROM chip, which is embedded with unique number, media access control (MAC) and Address. The device is identified on the LAN network via the unique MAC address. NIC is both a physical layer (OSI layer) and data link layer (layer 2) device that is used by either connecting to the cables or wireless.
Reasons for network controller failure in Toshiba® Tecra® A11
When the Boot Order settings or BIOS setup in the motherboard is incorrect, it usually gives errors related to network controller in Toshiba® Tecra® A11. For example, PCI Fast Ethernet Controller v2.13 error (PXE-E61: Media test failure, check cable error) relays the BIOS inability to locate hard disk drive and thus every diver installed onto it. Pre Boot Execution (PXE) error occurs when the system is trying to boot from a remote server using the network card. A corrupted hard drive leads to incorrect BIOS settings, which in turn contributes to network controller failure. Hard disk failure compels the system to boot from the network, and BIOS inability to recognize the driver or the command results in boot errors like Initial Boot error (Intel UNDI, PXE-2.0)
Ensure the hard disk drives are powered on and well-connected and configurations like BIOS Setup and Boot Order settings are correct. Run OEM supplied diagnostic to check the viability of the PCI Ethernet Card. Pre-Boot Execution error can be resolved by replacing the hard drive and re-installing the operating system and setting the correct BIOS settings. Since the laptop seeks to boot from server upon failure of hard disk driver, the system may not be configured to the boot from remote server using the network card, and therefore, the PXE-E61 Media test failure error. Initial boot error can be fixed by loading the original BIOS factory settings and re-formatting the disk drive.
