* Not all features are available in all editions or versions of Windows. Systems may require upgraded and/or separately purchased hardware, drivers and/or software to take full
advantage of Windows functionality. See microsoft.com.
1. This product is low-halogen except for power cords, external cables and peripherals. The following customer-configurable internal components may not be low-halogen: 3 ½" SAS
HDDs and LSI 9217-4i4e SAS ROC RAID Card. Service parts obtained after purchase may not be low-halogen.
2. Maximum memory capacities assume Windows 64-bit operating systems or Linux. With Windows 32-bit operating systems, memory above 3 GB may not all be available due to
system resource requirements.
3. Thunderbolt is new technology. Thunderbolt cable and Thunderbolt device (sold separately) must be compatible with Windows. To determine whether your device is Thunderbolt
Certified for Windows, see thunderbolttechnology.net/products.
4. Some vPro functionality, such as Intel® Active management technology and Intel Virtualization technology, requires additional 3rd party software in order to run. Availability of
future "virtual appliances" applications for Intel vPro technology is dependent on 3rd party software providers. Microsoft Windows required.
5. SATA hardware RAID is not supported on Linux systems. The Linux kernel, with built-in software RAID, provides excellent functionality and performance. It is a good alternative to
hardware-based RAID. Please visit h20000.www2.hp.com/bc/docs/support/SupportManual/c00060684/c00060684.pdf for RAID capabilities with Linux.

New performance settings
Processor snoop modes
The Xeon E5 v3 processor supports four different snoop modes: Early Snoop (also known as:
ES mode), Home Snoop (a.k.a.: HS mode, Broadcast Snoop), Home Directory Snoop (a.k.a.:
Directory Snoop, Directory Mode, HD Snoop), Home Directory OSB Snoop (OSB = Opportunistic
Snoop Broadcast) (a.k.a.: Directory OSB, Opportunistic Snoop). The M60 BIOS allows Early
Snoop and Home Snoop.
Security defaults
Security settings have a separate default, accessed from the BIOS GUI under the Security menu.
New Secure Boot key
The Secure Boot key exchange key (KEK) used to sign HP UEFI applications has been updated.
HP-signed applications using the older KEK will not run when Secure Boot is enabled; this
includes older versions of HP offline diagnostics. The two KEKs common to all vendors
(Microsoft Windows and UEFI CA) are unchanged.
Changes to replacement motherboards
All motherboard replacements will prompt the user to enter specific information (e.g. the serial
number) upon first boot. The system will not accept BIOS passwords and will require user
intervention to boot to an OS until the requested information is entered by the end user.
The M60 BIOS also supports System Manufacturing Commands (SMC), which can be used to
modify settings normally accessible at the factory. SMCs can only run on predetermined units
for predetermined purposes and are digitally signed to prevent from tampering. There is a
Computer Setup option to disable SMCs.
