Hello my fellow admins,
Just wanted to let you know that if you get the error message “Error loading /tools.t00 Fatal error: 10 (Out of resources)” when trying to install VMware’s ESXi 5.5 hypervisor on a Cisco UCS C240 M3 SFF rackable server with 1 or more NVIDIA GRID GPUs in it, just follow the next steps to fix it:


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



Hopefully you will solve this issue by yourself, not like me, after a couple of days with help from my Cisco technical friends :)

Apparently, the error cannot be reproduced on the same system but with no GPUs, or on ESXi 5.1. Cisco told me that they’re working with VMware on this one and hopefully they will create a more fashionable way on getting the systems up and running with ease.

Good luck!
