The PC2-LIMBO is a low power 4HP/3U CompactPCI® CPU board, equipped with an Intel® Atom™ E6xx series 1.6GHz processor, available on request for the industrial operating temperature range. The PC2-LIMBO front panel is provided with two Gigabit Ethernet jacks, two USB receptacles, and a DVI connector for attachment of a high resolution digital display.
The PC2-LIMBO is equipped with up to 2GB soldered RAM for rugged applications. An on-board CFast™ host connector is provided for attachment of a 3Gbps SATA SSD module. In addition, a microSD card holder can accommodate a low cost industrial microSDHC Flash card. Further more, several SATA based low mass storage expansion modules are available as an option. The PC2-LIMBO is equipped wit a set of local expansion interface connectors, which can be optionally used to attach a mezzanine side board. A variety of expansion cards is available, e.g. providing legacy I/O and additional PCI Express based I/O circuitry such as SATA and Gigabit Ethernet, or a secondary video output. Most mezzanine side cards can accommodate in addition a 2.5-inch drive.
Typically, the PC2-LIMBO and the related side card would come as a readily assembled 8HP unit. As an alternate, Flash based mezzanine storage modules are available that fit on the PC2-LIMBO while maintaining the 4HP profile. The C47-MSATA module e.g. accommodates two mSATA SSDs and can be operated in RAID mode. The C42-SATA module is provided with a 1.8-Inch Micro SATA SSD up to 800GB.

2017-02-01: BIOS release, Build #094 production
– Added Setup option to execute a fixed delay at the early beginning of POST
Setup (F2): Advanced -> Boot Configuration -> Execute Delay after Reset
Available options are: Disabled (no delay), 100ms (Default), 250ms, 500ms, 1s, 4s, 12s or 30s
If enabled, it allows certain devices to finish its internal initialization before
POST has access to these devices. The delay is indicated by a red blinking LED GP
in front panel of PC2-LIMBO.– Added Setup option to execute an additional reset on CompactPCI bus
Setup (F2): Advanced -> Boot Configuration -> Additional Reset on cPCI Bus
Available options are: Disabled (Default), Enabled
If enabled, an additional bus reset is executed on CompactPCI (Classic and PlusIO)
during early board initialization. This possibly solves power-up problems of certain
PCI devices. Note that this reset increased boottime by approximately one second
to allow PCI devices to reinitialize itself (PCI specification Trhfa parameter).========================================================================================
2015-04-24: BIOS release, Build #092 production

– Increased number of history screens for UEFI shell from 3 to 20
– Switched off red blinking LED GP immediately after Reset
– Fixed a bug in USB OHCI driver which sometimes prevented a boot from an USB device
========================================================================================
2013-01-15: BIOS release, Build #088 production
– Changed Ethernet LED behaviour of EG20T Ethernet controller (top RJ45)
Top LED signals this: No Link = LED is off, 1Gb Link = LED is constant Orange,
100Mb Link = LED is constant Green
Bottom LED signals this: No Link = LED Off, Activity = LED blinks Green with a blink
rate of around 1.5Hz
Two error cases can now be observed:
Case 1: In case of no Ethernet Phy is detected, bottom LED is off and top Orange LED
blinks with a rate of around 6Hz.
Case 2: If unexpected OUI is read from Marvell Phy (88E1119R), bottom LED is off and
top Orange LED blinks with a rate of 12Hz.– Show an error message if no Ethernet Phy at EG20T is detected
