I am trying to install ESXi 5.5 to a computer that ESXi 5.1 is installed before. I am doing installation using the CD-Rom. After I select the boot options in the boot menu, installation starts. After a while, it stops and gives following error. Error loading /tools.t00 Fatal error: 10 (Out of resources)

Can anyone know about this error and help me please? Thanks in advance :)

  • Are you doing a wipe or upgrade of the existing server and does the server adhere to the HCL? – Chopper3 Jan 30 '14 at 14:49
  • I think server is not adhere to the HCL. I am doing a wipe. – user1243987 Jan 30 '14 at 14:59

    Well...can you guess what the problem might be, and what we're going to suggest? This isn't a site for experimenters, we're all pro-sysadmins, we like to stick to the HCL. – Chopper3 Jan 30 '14 at 15:07

Follow these steps:

  1. Go to System BIOS (Press F2)
  2. PCI configuration > MMCFG
  3. Change the value from Auto to 2 GB
  4. Change the value of Memory Mapped IO above 4 G to Enabled
  5. Save and reboot the system
  6. Installation will complete

These instructions were formerly posted here although that page seems to be gone now.
