Can not enter the BIOS

Hello, I am trying to access the BIOS in a VM

The option "Power on to BIOS" just boot's the OS

Adding the line "bios.forceSetupOnce = "TRUE"" to the .vmx also does nothing and the OS just boots

Adding the line "bios.bootDelay = "5000"" again does nothing and the OS just boot's.

Is there anything else I can try? I really need to access the BIOS or someway of booting from a CD without booting the bios

Thanks in Advance
