Fail to download TFTP Download with UEFI firmware, where in BIOS works perfectly fine

[maksimu5]

Hi there

 

I am new to this forum and generally to SCCM (more or less) especially administration bit of it

 

Basically i've got a problem deploying TS to a Panasonic CF-AX3 (i know this brand doesn't help at all) in UEFI mode where BIOS mode works perfectly fine i am getting the following error below on WDS/DP

 

##################################################

The Following Client failed TFTP Download:

Client IP: xxx.xxx.xxx.xxx

Filename: \SMSImages\CWH00005\boot.CWH00010.wim

ErrorCode: 1460

File Size: 222221392

Client Port: 11259

Server Port: 57706

Variable Window: false

As far as i can comment on the issue following points are below:

1. We use Win server 2012R2

2. Sccm2012R2

3. one MP and one DP on the same network

4. Hotfix KB2905002 has been applied

5. Boot image is extremly slow

6. Boot image is WinPE5.0

Basically once WinPE started it downloads boot.sdi followed by CWH00010.wim and that's where it fails with an error 0x0000001 can't connect: A required device isn't connected or can't be accessed

Any help with this one, funny enough i can load Dell at a snail pace with UEFI enabled

Any suggestions?
