5 Benefits of a Custom BIOS

A variety of custom BIOS (Basic Input/Output System) and software solutions can be configured in your rack mount server or workstation to support your particular requirements and needs.

The benefits of a custom BIOS are many, but mainly, a custom BIOS can tweak or tune an existing solution, dramatically overhaul the bootup process to enhance security, increase system manageability, support high-end co-processing hardware, and optimize system performance.

In this blog post, we'll discuss five ways custom BIOSes can enhance your rugged computing solution and what to look for in a computing solutions provider offering them.

1. Security

In today's environment of continual software vulnerabilities, bugs, and patches, staying on top of the latest security technologies and resolutions is paramount. Looking for a rugged computing solutions provider that partners with companies like Intel and AMI to continually monitor for security notifications, patches, and enhancements is essential because the provider will be able to implement related fixes and updates quickly and efficiently, following regression testing and validation.

This includes security fixes and updates related to:

  • BIOS
  • Firmware
  • UEFI specification updates
  • Intel AMT
  • ME
  • Other technologies

Furthermore, you should also be able to request additional security enhancements, such as the disablement of certain bootable devices like USB or optical drives. A custom BIOS from the right computing solutions provider can lock down BIOS parameters and controls to provide increased security and prevent unintended usage. Additionally, a highly secure and reliable BIOS update process should be in place for every rugged computing solution you purchase.

2. System Manageability & Monitoring

Any worthwhile computing solutions provider will have implemented a BMC solution for monitoring a rack mount computer's overall health and condition.

BIOS customizations further enhance the standard IPMI solution, including reporting boot sequence progress, FRU data collection/reporting, and system error notifications. PCIe link health status (correctable/uncorrectable errors) and DIMM status, including ECC detection/correction, patrol scrub, and demand scrub states, can all be reported to the BMC for further processing by system management software.

Additionally, custom SMBios table entries are possible, including memory DIMM SPD data, Ethernet port configurations, and serialization data for manufacturing traceability. These tables can expose hardware features of the system to the OS and/or BMC for enhanced detection, optimization, and reliability.

3. PCIe Enhancements

As data centers see an expansion of various high-performance hardware devices supporting cloud computing, artificial intelligence, machine learning, and encryption technologies, PCIe performance can become a bottleneck in overall system capabilities. From NVIDIA and AMD GPUs to Xilinx and Altera FPGAs, being able to trust hardware and software engineers that can work closely with you to improve and support high-performance PCIe hardware endpoints is crucial.

BIOS customizations can provide custom PCIe bifurcation settings, as well as equalization adjustments for tweaking emphasis/de-emphasis, improving signal integrity, and reducing link errors. Also, as PCIe buses increase in size, the BIOS can be enhanced to support increased capacity on the PCIe bus. These enhancements can be particularly important with solutions like large backplanes or expansion chassis that can greatly increase the PCIe bus topology in both size and complexity.

4. BIOS Optimizations

The mainline BIOS shipped with your rack mount computing solution should support a wide variety of hardware and software combinations. This flexibility and robustness should provide a solid, reliable platform for supporting many configurations of CPUs, PCIe devices, USB attachments, and other miscellaneous peripherals.

Some customers settle on a fixed set of hardware requirements and can request BIOS optimizations for increasing reliability, reducing boot times, and optimizing performance. Additionally, BIOS setup default values can be set according to the customer's requirements, including hiding any combination of settings or controls, whether it be for security concerns, system stability requirements, or a streamlined user interface.

5. Legacy Support

Many times, the system BIOS is required to support legacy devices such as PCI endpoints, PS/2 devices, or monitors with limited capabilities. Custom IRQ routing and PCI-to-PCIe conversion nuances can require tweaks to the BIOS, or a widely-deployed monitor may require a specific, non-standard resolution. Look for a computing solutions provider that can meet these unique customer requirements down to the last detail.

Add a customized BIOS to the mix, and you got yourself a very powerful and flexible rackmount computer that ensures system stability and reliability for years to come.

Look for manufacturers that offer custom BIOSes

Doing business with a high-performance computer manufacturer that offers BIOS customization lets you, the customer, request a feature-specific BIOS that fits your program's or application's unique firmware and booting needs.

Some manufacturers don't offer BIOS customization, which puts you at the liberty of any BIOS changes on their end and may even leave you without some of the benefits listed above.

At Trenton Systems, we employ BIOS designers who work with Insyde and AMI source code to craft unique and tailored BIOS solutions for customers. These tweaks include, but are not limited to, custom boot options, port enable and disable features, among other characteristics.

Here are five advantages we have that are associated with controlling the BIOS design in-house:

  1. We make our own processor boards: Before a new Trenton processor board is released, there's a lot of time spent during design to ensure that the boards undergo a proper bring-up. We typically don't know how the end customer will use our processor boards in their application, so our BIOS must remain flexible enough to handle a wide range of PCIe expansion cards, USB, and Ethernet. The BIOS must also be able to enumerate a wide array of memory options.
  2. Firmware encryption: For security-conscious applications, Trenton can encrypt the firmware on certain processor boards via Intel's Platform Firmware Resilience (PFR). A unique key is the provided to the customer so that they are the only individual who can modify the processor board's firmware.
  3. Large number of PCIe devices: On occasion, customers will have a specific application that requires a large number of PCIe expansion or NVMe drives. There's only a certain amount of space allocated to enumeration, so for situations like this, Trenton's BIOS designers can work directly with customers to ensure all devices are set up properly.
  4. Small customizations and tweaks: For minimal or no charge, customers do request custom load screens, such as those with their logo, or a custom boot order, depending on the hard drive to which they default. These upgrades are typically completed very quickly.
  5. Revision control = same unique BIOS for years: Trenton's BIOS revision control process ensures that all future purchases from a specific customer will include their custom BIOS.

Trenton Systems' ruggedized computing solutions are all built to the highest standards, and we provide a variety of custom BIOS and software solutions for supporting our customers’ particular requirements and needs.

A dedicated team of software and hardware support engineers work closely to provide a feature-rich, generic BIOS solution that supports a wide array of SHB, backplane, hardware, and software combinations for rack mount servers and workstations.
