- | This error shows when ''ACPI'' tables can't be modified by iPXE. when using ''sanboot'' command in EFI. | + | This error indicates that your UEFI firmware has a bug that prevents the installation of the iSCSI boot firmware table (iBFT). Switch to booting in "legacy" BIOS mode rather than UEFI mode. |
- | See [[http://lists.ipxe.org/pipermail/ipxe-devel/2017-April/005550.html|Technical details]] | + | |
- | The debug message is: | + | If you are unable to switch to "legacy" BIOS mode, then you will need to contact your UEFI firmware vendor for a fix. |
- | EFIBLK has no ACPI table protocol | + | |
+ | You may also work around the bug in your UEFI firmware using the ''%%--no-describe%%'' option of the ''[[:cmd:sanboot]]'' command. This will allow iPXE to boot from the SAN device. However, since the UEFI firmware bug prevents iPXE from installing the iBFT, the booted OS will not be able to automatically locate the iSCSI disk. | ||
