You can use up to 1GB of RAM on PE2 - PE4 by modifying the WinPECacheThreshold value. But, on PE5 you can only use 512MB.

Did you get results other than what we found back in 2009?

As a side note, are you sure-sure that:

Originally, the XP-based PE 1.0 functioned with just that 3MB read-only disk. Many applications expected to be able to write temporary files to the OS volume, though, eventually leading to the File Based Write Filter (FBWF) being added in the Vista-based PE 2.0.

Windows XP based PE's (i.e. PE 1.x) actually ever used the 3 Mb "read only disk"?

(surely they didn't have BOOTMGR or the \boot\BCD)
