Try restarting the landesk mtftp and pxe services on your PXE reps. If that does not work remove and redeploy the pxe rep.
I have tried both of those actions already.
I restarted the Reps, undeployed and redeployed about 5 times. The mtftp service is functional as all other devices will get the image without an issue.
The machine I'm using has an SSD with no apparent settings to change the mode (IDE, AHCI, etc). Perhaps it's not getting the image because it can't write to the drive?
I have the same exact problem with a T430, model number 2344. Mine PXE booted and grabbed an image the very first time, I then checked on the drivers and have to install a bunch of drivers to make the image complete. I then grabbed the drivers using Driver magician so I could add them to my Hardware Independant imaging, now eveytime I try to PXE boot this machine, I get the same problem where it goes through and has the blinking cursor under Boot Server IP and the IP address. I too have redone my PXE reps. I can take a Dell E6400, PXE boot it and lay an image just fine, so that is not the problem.
I had this same problem with our newest batch of T430's. It's bug in that machine's BIOS. We updated to Bios Rev 2.59 (dated 11/21/13). Fixed the problem.
Well my cure for the T430 Series seams to be another BIOS Update to 2.59 that came out. Now I am PXE booting like the rest of my machines. Now I get to fight with Hardware Independant Imaging to get my drivers to load..hopefully
Thanks to tdocekal!!!!!!
LANDesk support informed me that the following applies.
PXE Boot menu differences:
PXE Menu = mtftp transfer
Privisioning = tftp transfer
The issue for me is that the mtftp does not work for the Lenovos. The tftp appears to function without an issue. I have modified the boot.wim file on my reps to load PXE Menu either way so I have a work around for the time being. It does indeed sound like it's an issue with the BIOS on the units and their incompatibility with the mtftp transfer of the files.
This link has some addtional information as well.
