Unable to boot a Blade BL685c on WinPE 3.0

[Mikael Rönnbäck]

I have an enclosure with 1 BL465c and 1 BL685c , I use ILO2 on these to boot a virtual CD/DVD image to install the OS.
Both ILO2 have firmware 1.78

When booting WinPE 2.0 (for Windows 2008) on both works fine, when booting WinPE 3.0 (for Windows 2008 R2) only BL465c works, the BL685c blade does not find the virtual CD mounted via ILO (which I just booted on).

Are there differences in ILO2 depending on which hardware model they run on ?

And has anyone been able to boot WinPE 3.0 on BL685c and if so, how ? Add any additional drivers or what ?

I found out a workaround, the BL685 needs to downgrade ILO2 FW to 1.70, then booting and installing Windows 2008 will work.

No need to downgrade ILO2 FW for BL465.
