The Preboot Execution Environment (PXE) is an industry standard client/server interface that allows networked computers that are not yet loaded with an operating system to be configured and booted remotely by an administrator
the Preboot Execution Environment(PXE) specification is a client-server environment that boots a software assembly retrieved from a network
It a method of booting endpoints using network boot ROM presents in Network card
Yes all above answers are correct. when PXE was introduced not many systems have the capability to boot from netwok.
is a method of having an end computer (client) boot using only its network card.
it is possible to circumvent the normal boot procedure
The Network Interface Card (NIC) of the machine triggers a DHCP request. DHCP server intercepts the request and responds with standard information (IP, subnet mask, gateway). In addition, it provides information about the location of a TFTP server and boot image. PXE (Preboot Execution Enviorment).
Pre eXecution Environment is a method of having an end computer (client) boot using only its network card.when using PXE the boot process is changed from the normal order to:
Power on –> BIOS –> Network Card’s PXE stack –> Network Boot Program (NBP) downloaded using TFTP from server to Client’s RAM –> NBP’s responsibility to perform the next step 2nd stage boot.
its a method of booting computers without operating system to be configured remotely
The Preboot Execution Environment of PXE is used for unattended OS installations on a group of computers connected to a specific network.
PXE (Pre eXecution Environment),is a method of having an end computer (client) boot using only its network card. As long as the computer in question is connected to the network (and supports this standard), it is possible to circumvent the normal boot procedure (I.E. Power on –> BIOS –> HD/CD) and do some nifty stuff starting from troubleshooting, to using a liveOS and even re-imaging the machine
Power on –> BIOS –> Network Card’s PXE stack –> Network Boot Program (NBP) downloaded using TFTP from server to Client’s RAM –> NBP’s responsibility to perform the next step (a.k.a. 2nd stage boot).
The Preboot Execution Environment (PXE) which uses client/server interface that allows networked computers to boot from preconfigured images stored at image deployment server/ PXE Server.
