-
- if you want to keep WinWord running at all times, you may want more
- memory. Remember that Windows sessions eat memory (at least 2 MB in
- most cases)
-
- Also note that some games may give it problems. Things like CompuShow
- should be run in full-screen sessions, but that's not much of a
- problem.

-
- I'd recommend an AMD-386/40 motherboard. I've heard strange things
- from the 486 users regarding speed. I don't know why.
-
- >What size of cache should I get on the motherboard?
-
- You can expect to get 64K. It should be sufficient, although larger
- ones may be available. I question the need for larger caches in most
- situations, though.

-
- A local bus slot will be nice if you have local bus peripherals to
- plug into them. Most local bus devices currently out are video boards
- and hard drive controllers. If you're not going to use it, it's a
- waste of money.
-
- Also note that accelerated graphics (like the ATI Graphics Ultra) will
- speed things up more than a local bus sVGA board.
-
- >Other equipement (if relevant):

-
- What's the speed? Faster drives are always better. Remember that
- about 30MB of the disk will be used for OS/2 if you install
- everything.
-
- > ATI VGA Wonder XL with 1MB
-
- A good choice. Get Joel Armengaud's sVGA drivers for it. They'll get
- you 1024x768x256 res. ATI also has drivers - they're slower, and
- they'll get you 1024x768x16 res. Note that you'll lose seamless
- Windows at these resolutions.
-
- Currently, the only non-VGA driver which provides seamless Windows is
- the Trident driver (for Trident boards, of course), which gets you
- seamless Windows at 800x600x16.

-
- Be sure that it's set to an unused interrupt. (Usually IRQ-5). The
- factory default (IRQ-7) is used by most printer ports.
-
- > SupraModem 2400 MNP
-
- If you already have COM1: and COM2: ports on your motherboard, you'll
- need to disable one or set the modem to an unused interrupt. COM1
- normally uses IRQ-4; COM2 normally uses IRQ-3. If the modem is
- external, plugging into a serial port, then this isn't a problem.
