S2600-CW2 vmware ESXi 5.5 hangs on ACPI initialization -- Boot loop

Jump to solution

Hi there,

I tried to install ESXi 5.5 on my S2600-CW2 board. The installation process breaks up on ACPI initialization and boot again.

Upgrading to the latest Firmware 01.01.0005 (from 0003) didn't solve it. There is no RAID-Controller card, only the two CPUs and one USB-Stick for installing.

For the S2600-CP2 board, there is a recent version of the BIOS that works:

Any ideas how to solve it?

Just get the answer in the vmware community forum:

In BIOS > Advanced > PCI configuration > MMIO above 4GB > disable

Tested with s2600CW2 - ESXi 5.5.0 U2

Thank you for the update. I just received a report from one of our clients and it seems that he was able to install the Operating System just fine after these changes.
