case with my PS/2-E... it's a 486SLC - a laptopish
386SX with some
extensions - thus a max 16M address space. In my case, there's a
jumper to allow direct addressing of the RAM on the video card to
enhance the "pep" of windowing environments, leaving 12MB of system
RAM visible, or, you can have access to all 16MB of RAM, but pokey
bitmap graphics. Obviously, I chose 16MB and poor bitmap performance
since I am not running a windowing environment. Unfortunately, I'd be
surprised to see such a jumper on a laptop.
Of course I would also choose to have all the RAM to the operating
system and none for video. I whish there is a way to do so on this
laptop... I'll try to figure it out. Does somebody here knows?
So one question to ask is, is that laptop a 486SX or
DX, or is it a
486SLC. Those are two entirely different chips.
It's a Compaq Contura 410CX, a 50MHz Intel i486DX2, acording to
