November 4, 20241 yr Hi, I've an old NAS I want to try out UNRAID on it. It only has legacy BIOS boot, no UEFI. The issue with it is, when it boots from USB2 ports it seems to only function as 1.1 due to bios issue, and it can not boot from the USB3 ports. While booting UNRAID from USB2, it will try load the bzroot but eventually reboots. Tried OMV on the USB2 ports, it does load however takes several minutes to complete the boot. After that it functions as normal. So I wonder if I can plug the UNRAID usb drive on the USB3 ports, and have a GRUB4DOS usb drive on the slow USB2 ports to load syslinux/UNRAID? If so how to write the grub4dos menu command line? Thank you. Edited November 4, 20241 yr by rampage
November 4, 20241 yr Author To answer myself, I found plop boot manager can have the USB devices setup properly then load other systems from USB drive. This solved my problem, now BIOS boots to plop boot manager, then boot the unraid USB drive and it is pretty fast. And yes its Gigabyte motherboard, it seems they are common problem with gigabyte
