How do you dump your computer BIOS?

There are a few methods for doing this:

Uniflash
Uniflash is a free program that supports dumping the BIOSs from most motherboards and even some graphics cards. You will need to be able to boot from a floppy disk or a bootable USB flash drive (it runs on MS-DOS).

FlashromFlashrom is a Linux program that can dump Flash chips from some Flash chips. It does not support quite as many as Uniflash, but supports more modern ones. Linux is probably also easier to boot from on modern computers than MS-DOS (you can boot MS-DOS from a CD, but then you'd have nowhere to save the files).

No. The term serial port refers to the older 9 or 25 pin, male connectors on the back of a PC. They were used for connecting to modems, certain printers, and mice.

micromegakaryocytes are typically seen in the peripheral blood in Myelodysplastic Syndromes (MDS) which are considered "pre-leukemia" syndromes because a high proportion of them progress to acute leukemia.

Micromegakaryocytes are caused by dysmegakaryocytopoiesis, meaning the bone marrow is not making normal megakaryocytes. Other megakaryocyte abnormalities may include large megakaryocytes that lack normal nuclear segmention, megs with two or more small unconnected nuclei, and "mononuclear" megs that lack normal nuclear lobation.

Shutting down your computer can cut energy by how much?

It's estimated that shutting off your computer (and monitor, obviously) when you leave the house to go to work and especially overnight can save you over $200+ a year on electricity bills.

And it's a myth that's been debunked that shutting off computers shortens their life span.

Computer parts have advanced to the point where your computer will be LONG obsolete way before the cooling and heating/expanding and contracting effect of powering it on or off would begin to impact performance or damage it.

So go ahead and shut it off. Save some energy, money and help the environment.

Will WIFI work with dial up Internet?

Practically speaking, no. Even if you had some way of connecting a dial-up connection to a wireless router, the already limited bandwidth would be much too slow to be used by more than one person. And since connection speeds on wireless routers tend to drop off the farther you are away from it, the connection quality would become unusable rather quickly.
