Thank you, Younas. -----Original Message----- From: edk2-devel On Behalf Of Pathan, Moh= ammadYounasKhan Sent: Thursday, March 7, 2019 11:07 PM To: edk2-devel@lists.01.org Cc: Raju, SriramKumar; Poosapalli, Karunakar; S, Shekar Babu Subject: [edk2] Regarding PXE boot NACK error. [EXTERNAL EMAIL]=20 Hi All, When one of DHCP cum PXE server which is not configured properly and return= s NACK. When PxeBcDhcp4Dora() returns EFI_TIME_OUT and PxeBcSelectBootPrompt () ret= urns EFI_NOT_FOUND, do we need to abort the DHCP transaction or not in PxeB= cDiscoverBootFile()? Or should we retry? Currently it calls PxeBcDhcp4BootInfo() to get the boot info. PxeBcDhcp4CallBack is getting called 2 times: Dhcp4Event: 0x1 (Dhcp4RcvdOffer) Dhcp4Event: 0xC (Dhcp4Fail) Do we need to retry PxeBcDhcp4CallBack() for more times even if it is Dhcp4= Fail? EfiPxeLoadFile() -> PxeBcLoadBootFile () -> PxeBcDiscoverBootFile() -> PxeB= cSelectBootPrompt() Attached the transaction debug log for reference. Please share your comments. Thank you, Younas.
