Another possibility, if laptop has an eSATA port, is to install FreeBSD on an eSATA hard drive, or SATA hard drive in a hard-drive enclosure that has eSATA.

Only current brand of eSATA hard drive that I know is Micronet Fantom (

It may be necessary to install GRUB2 to a USB stick and boot from that; from there it should be able to boot anything on an eSATA hard drive.

On my computer, eSATA looks just like SATA to my motherboard/BIOS/UEFI, and FreeBSD and NetBSD work more dependably on eSATA than USB 3.0; I don't know if NetBSD even works on USB 3.0.
