Looks really cool.

One thing, though:

That doesn't seem particularly tiny to me. I have an old Pentium II box with 32 MB of RAM that runs the latest release of OpenBSD with X, and I don't consider OpenBSD particularly tiny, either.

At risk of sounding like a crotchety old man, these are sad times to be living in when 64 MB is considered tiny.

In all fairness, I think tiny in this case refers to the fact that the OS is only 200kb. From the openBSD install guide:

OpenBSD can be installed in as little as 512MB, but using that small of a device is something for advanced users.

It might say that, but to be honest I had no difficulties installing on my box with 32 MB RAM. I didn't even have to do anything special; I just followed the normal installation procedure. It's not blazing fast by any means, but it does boot and it does work :)

Disk size, not RAM. How large a hard drive are you using?

Ah. The HDD has 4 GB. This thing was top-of-the-line back in '98 when it was purchased ;)

Classic DOS barely took up kilobytes of memory. I think that qualifies as "tiny". Megabytes is downright bloated by comparison.

Considering this is written in assembly, what is all that memory used for?

Well, for one thing, it's a graphical OS.

What does that have to do with anything? Windows 3.1 had a minimum RAM requirement of 1 MB. The base model of the Apple Lisa 2, which featured a graphical OS, had 512 KB of RAM. It's possible to have graphics without requiring so much RAM.

Because I don't have a proper heap yet. And so everything takes up 2 MB pages.

Well, graphics rendering can take up many MB on its' own...
