21824: Boot from Acronis PXE Server Fails with "Acronis Loader fatal error: At least 512 Kb of conventional memory required to start Acronis Loader"

This article applies to:

  • Acronis Backup & Recovery 11
  • Acronis Backup & Recovery 10
  • Acronis Snap Deploy 3

Symptoms

  1. You install Acronis PXE Server and configure machines to boot from it;
  2. Machines fail to boot from Acronis PXE Server with the following error:

    Acronis Loader fatal error: At least 512 Kb of conventional memory required to start Acronis Loader

Cause

Incorrect work of Intel RAID in BIOS.

During bootup, Intel RAID consumes a considerable amount of memory and the remaining memory is not enough for loading the PXE image from network.

(!) This issue is not specific to Acronis PXE Server only; it occurs with other PXE servers as well.

Solution

In the computer BIOS, change SATA Operation mode from RAID On to any other mode.

As a workaround, you can use Acronis Bootable Rescue Media to boot the machine instead of Acronis PXE Server.
