Legacy mode BIOS
I have an ups-aplp4f-a20-08128 motherboard, and in its BIOS mode, there is a CRB option. Within CRB Advanced, there's a CSM Configuration option that includes a Boot Option Filter. This option can supposedly switch between legacy or UEFI mode, but it doesn't work. No matter how I adjust it, the boot list still doesn't show any system disks that boot in legacy mode. Given how long it's been, the new BIOS should support booting from legacy mode system disks by now, right? Although I have a UEFI mode image that I can use, it can't adjust partition sizes and occasionally freezes or crashes, which is really frustrating. So, I'm asking whether the BIOS now supports booting in legacy mode, or how to configure the current 6.4 BIOS version to support legacy mode booting?

Hi @pcmp
Legacy mode refers to legacy VBIOS, which is no longer supported by APL.
It's now uEFI-only.Best Regards,
