If you think it does not mean that - then please enlighten everyone
as to what it means :) :)


Can I create a disk with msdos partitioning scheme,
none of the partitions marked as bootable, and have bios
quickly skip over it to the next device in the boot sequence?

So far it looks like the answer is "no" or "it depends on your BIOS."

Both SeaBIOS and your Dell BIOS, based on what we've seen, will attempt to use the boot sector of a disk with a valid MBR, even when the boot sector is all zeros. That's consistent with all of the documentation I can find. It's possible that other BIOS might skip an all-zero boot sector, but we don't have any documentation of which systems behave that way.

However, also based on testing, it seems that if you used GPT for your partitions, then BIOS would skip over the drive during the boot process. So, maybe that's a solution? The only reasons I can think of to use MBR are a) you have an operating system that can't read GPT and b) you need to boot from the drive under BIOS. I don't think either of those apply to you.
Since my internal drive is dual boot, I do need to boot an OS that does not
recognize GPT :(

So, if I use GPT, then, bios will skip over it if it comes before the internal boot disk?

I will test that on a usb disk.
