The 5150 has an 8088 running at 4.77 MHz.  The very old models can
accomodate 64K RAM on the motherboard.  Later models use 64K DRAMS
for 256K on the motherboard.

Assuming you have the original IBM BIOS chip, you can tell if it can
accomodate a hard drive by looking on the back of your computer.
If there's a large B with a circle around it stamped in ink, then
your BIOS can accomodate a hard disk.  If it's not there, then
you need an upgraded BIOS.  Note that early PC's can all USE
a hard disk, but not necessarily boot from it.  If you don't
mind booting from a floppy, that might be an appropriate
solution.

An intelligent disk controller with on-board BIOS support
might boot, but I doubt it.
