OpenBSD questions: (1) memory; (2) Mitsumi CD-ROMs

[sgordon at kenan.com (Seth Gordon)]

I have an 486SX machine that's at least five years old, and I'm trying
to install OpenBSD on it.  I have installed a new hard drive, a
not-so-old CD-ROM, and a new 3.5" floppy drive.  (When I got the
machine, it had a 5.25" drive.)

Two questions about getting this thing running:

(1) The machine has 4 MB RAM, and nobody makes the kind of SIMMs it
uses  any more (SIMMs of 30-pin, 1-MB, parity RAM).  I just want to
use this thing as a firewall and mail/news server; for these purposes,
how much will the limited RAM slow me down?  And does anyone out there
want to sell me 4 MB of obsolete RAM?

(2) The CD-ROM is a Mitsumi.  According to the footnotes on the
OpenBSD/i386 page, support for the Mitsumi CD-ROM is in the "generic"
kernel, but not in the kernel on the installation floppy.  So how to I
make an installation floppy that *does* support that device?
