I'm using coreboot with seabios on Thinkpad T420. I found that sometimes USB disks do not show up on first code boot (press the power button), possibly due to slow on detection? If I press Ctrl+Alt+Delete a few times, they will appear in the list.
Recently I used clonezilla for backup and I was inspired by this feature. Clonezilla has the following screen that it will detection disks periodically until it find the disk. So I wonder could seabios implement features like this that after I press the ESC, the list will update periodically?
``` Every 3.0s: ocs-scan-disk 2020/03/21 03:22:25 You can insert storage device into this machine now if you want to use that, then wait for it to be detected. Scanning devices...
