A new security feature in laptops could help small and midsize businesses protect against advanced malware attacks.
What Changed
Dual BIOS technology, a security feature now available in select laptops, is gaining attention as a critical layer of defense for small and midsize businesses. The feature, which allows a laptop to boot from a secondary BIOS if the primary one is compromised, was confirmed in updated specifications from major laptop manufacturers as of October 24, 2026.
What Is Confirmed
Dual BIOS operates as a redundant firmware system, enabling a laptop to bypass a compromised primary BIOS by booting from a secondary, isolated BIOS. This design prevents malware from loading before the operating system, which can evade traditional antivirus tools and persist even after a drive wipe or reinstall. The feature is explicitly mentioned in technical documentation from manufacturers but is not widely advertised to SMBs.
Confirmed details include:
- Dual BIOS is a firmware-level security measure that mitigates attacks targeting the BIOS.
- Malware targeting the BIOS can bypass operating system-level protections, making dual BIOS a critical safeguard.
- The feature is available in newer laptop models from major manufacturers, though pricing and specific models remain unconfirmed.
Unconfirmed details include:
- The exact cost of laptops with dual BIOS.
- The availability of dual BIOS in older models or through firmware updates.
- The extent of compatibility with existing operating systems and security software.
What to Watch or Do Next
SMBs should evaluate whether their current laptops include dual BIOS technology, as it offers protection against advanced persistent threats (APTs) that target the BIOS. While the feature is not a substitute for strong passwords or regular software updates, it adds a critical layer of defense. Manufacturers have not yet released detailed implementation guidelines, so IT teams should monitor updates from vendors for further specifications.
