Important Information
Rolling back to a previous BIOS from 2.14.2 will cause a TXT trusted boot failure with TXT enabled. Since the Intel ACM's SVN (Security Version Number) was increased in BIOS 2.14.2 to address the Security Vulnerabilities CVE-2021-0559, CVE-2021-33123, CVE-2021-33124. The purpose of incrementing the SVN is to prevent executing an older ACM with the vulnerabilities.
- The INTEL ACM's SVN was also increased in the BIOS 2.9.4 since the 1st BIOS revision of this platform as well.
When using an Update Package (DUP) file or the UEFI Shell command (an EFI file) to update the BIOS version, the process takes longer duration. To resolve this issue, do one of the following:
- Update the BIOS version using an Out-of-Band (OoB) tool such as iDRAC--use GUI or run the RACADM command. See the iDRAC User's Guide or RACADM CLI Reference Guide available on the support site.
- Reduce the system memory capacity by physically removing the memory modules and perform the BIOS update and retry the operation.
When one or more PCIe devices are installed on the system and if the cards require more of limited legacy I/O resources, the system might modify the I/O resources causing it to restart automatically. The UEFI0256 error message is logged, and the system does not allocate the PCIe resources required. To resolve this issue, do one of the following:
- Remove the PCIe cards from the system that are not used to free up the legacy I/O allocation and provide more I/O allocation space.
- From the System Setup menu, disable to PCIe cards that are not used to free up the legacy I/O allocation.
When one or more PCIe devices are installed on the system and if the cards require more of Memory-Mapped I/O (MMIO) resources, the system might modify the MMIO resources causing it to restart automatically. The UEFI0256 error message is logged, and the system does not allocate the required PCIe resources required. To resolve this issue, do one of the following:
- Remove the PCIe cards from the system that are not used to free up the MMIO allocation.
- From the System Setup menu, enable the Memory Mapped I/O above 4GB option to free up the MMIO allocation.
NOTE: Before working inside your system, follow the safety guidelines listed in the Safety Instructions topic in the Installation and Services Manual of your respective server model available on the support site.
