If you are trying to install XP as a Virtual Machine in your ESXi host, you might get the following error during the initial Windows XP installation.
“Setup did not find any hard disk drives installed in your computer”
This mainly, because Windows XP doesn’t have the necessary drivers for it to see the ESXi host hardware. You will need to download the necessary drivers for it.
For BusLogic, you can download from vmware site.
For LSIlogic, you can download from the LSI site.
