You have to download the storage drivers for ESX 3.5.x and Windows XP when using the VMware LSI Logic Storage Adapter. Solution
Go to www.lsi.com/support and download the LSI driver for LSI20320-R. Make sure you get the Windows Hardware Quality Labs (WHQL) 1.20.18.00 driver for Windows XP (LSI20320-R_xp_50700_01034132IT_1201800_1005239.zip ).
Note: The newer driver, 1.28.03, works for ESX 4.0.
The driver download contains another zip file named symmpi_wXP_1201800.zip . Make a floppy image of the contents of symmpi_wXP_1201800.zip and insert this floppy disk when you are prompted for a driver disk during the Windows XP installation process.
