On this old dell (dual pentium), connecting the external
drive (a seagate 2TB external 2.5" "backup plus" drive.

When I got the drive, I connected it after booting into fedora.

Partition 1 contained some windows related stuff for backup.
I backed it up to another drive.

I partitioned the drive to two partitions only.
Partition 1 is the entire drive - minus 8GB).
Partition 2 is 8GB swap partition.
I formatted partition 2 ext4.

So far, so good.

Now, if I power up with this external drive connected (usb3),
all I get is a cursor at upper left corner.

If I disconnect the drive, reboot, then I get the Fedora boot menu,
almost instantly.
Before I select which kernel to boot, I connect this external drive
and boot the latest kernel.

All is well.

So, what has remained on the external drive to cause bios
to hang like that?

It's pretty common for the BIOS to, by default, try to boot external
media (CD ROM, USB, eSATA and such) BEFORE booting a local hard disk.
This is how you can boot a rescue CD or install software without
disconnecting your internal hard drive first.

If you ABSOLUTELY must have the drive attached at boot time, get into
the BIOS and change the boot order so the internal drive is tried BEFORE
your USB stuff. Remember, however, that if you do this, then you won't
be able to boot any external media unless you flip the BIOS back.

Thou hast been warned!
