How does the BIOS...

Oh and, one of my computer's boot screen looks much better than yours

Mines better,

One thing I noticed on both the images is that, there's no cursor. This means, this maynot be the text mode(?). It's possible to have text like fonts in graphics mode and moreover, tweaking video modes can give the same effect as the text mode but without cursor. Does this make sense?

Text mode and cursor are independent. There are several ways of hiding the cursor in text mode:
1. move it otside the screen, like 81x26
2. specify cursor shape start position after the end position (in vga regs, like row 16-15)

Brendan has more ideas on hiding the cursor. (Found via Google, "BIOS disable cursor", first hit. )

Yep, you guys are right, which means my logic doesn't make sense.

Ah, that Brendan's post .......
I don't use text mode but that looks useful.
