ESX/ESXi 4.1 Unable to install windows 2008 r2 sp1 since the windows is unable to find the installation disk (missing drivers)

Issue: When tried to install the windows 2008 r2 sp1 on an ESX/ESXi 4.x host it failed to find/see the disk due since it did not have the proper drivers to see the VMware virtual disks.
note: the scsi adapter selected was lsi sas controller. Tried to inject the vmscsi drivers from the floppy image but they were not recognized as the proper drivers. []

Resolution: There are 2 different windows 2008 R2 SP1 images of different size but with the same build number. The correct working iso is of 3.02 gb and the one which does not work is of 2.6gb.
working iso from msdn/technet:
File Name: en_windows_server_2008_r2_standard_enterprise_datacenter_and_web_with_sp1_x64_dvd_617601.iso
