Now that I finally tested ES40 write some notes about these machines.

Triggered that ES40 should 'just work by': gallatin

<para>The ES40 is a SMP system that can have 1 - 4 21264 Alpha CPUs.
With the maximum configuration of 32GB of memory these systems are
often deployed as heavy database servers and are also found in HPTC
compute farm environments.</para>

<para>SRM console code comes standard with the ES40.</para>
<para>ES40 comes with an ATA CDROM drive, but uses SCSI
harddisks.</para>
<para>Memory is divided in 4 memory arrays which each contain
a set of 4 SDRAM DIMMs. Each DIMM is 72 bit wide and of the 100MHz
speed variant. An array can contain 2 sets, so 8 DIMMs max per array.
The DIMMs live on Memory Mother Boards (MMBs). There are 2 MMB models,
with 4 and 8 DIMM sockets respectively. Each MMB provides half of the
256 bit memory bus width to the CPUs.
Given the myriad options for the memory configuration it is advisable
to check the system documentation for the optimum memory
configuration.</para>
<para>Dependent on the model variation the ES40 has 6 or 10 64 bit PCI
slots. This is basically just means the same backplane with less
connectors mounted.</para>
<para>ES40 has the same RMC remote power control as DS10 and DS20.
See the description of the RMC in the DS10 section of this document.
Most variations of ES40 have multiple power supplies, allowing
for N+1 redundancy. When installing CPU cards you must unplug all
power cords, the CPU cards receive standby power from the power
supplies. Maximum memory configurations need more than the default
number of powersupplies.</para>

EV6</literal> defined for inclusion in the kernel config
