U-boot bootloader, siv feem ntau ntawm cov khoom siv kos, sib koom ua ke TCP pawg thiab siv lub peev xwm rau khau raj remotely nrog xa cov duab khau raj siv HTTP raws tu qauv. Yav dhau los, tsuas yog UDP-raws li kev cai xws li TFTP thiab NFS tuaj yeem siv rau cov chaw taws teeb network booting. Nws cia siab tias kev txhawb nqa rau kev thauj khoom ntawm HTTP yuav ua kom yooj yim rau kev txhim kho cov kab ke, txij li HTTP servers muaj ntau dua thiab paub txog cov neeg tsim khoom.
Cov lus txib wget tshiab tau ntxiv los rub tawm cov duab ntawm HTTP hauv U-boot. Txhawm rau pab kom TCP pawg thiab wget hais kom ua, cov ntaub ntawv teeb tsa muab cov CONFIG_PROT_TCP, CONFIG_PROT_TCP_SACK, thiab CONFIG_CMD_WGET tsis. Cov phiaj xwm rau yav tom ntej suav nrog kev siv HTTPS kev txhawb nqa thiab kev koom ua ke nrog UEFI HTTP khau raj.
