I recently got a used 486/33 machine for $100.  I decided to try to get it
to run both Windows 95 and FreeBSD, so I could use it as a backup for my
Pentium system which runs both OSes.

My first problem came when I needed to put in an IDE controller with an
enhanced disk BIOS, as the BIOS on the motherboard did not work with
disks with more than 1023 cylinders.  It turned out that FreeBSD 2.1-RELEASE,
which is what I am running on my Pentium, will not boot if I have the
card with the enhanced disk BIOS in the System.  Someone posted a response
saying that it would work with 2.1.5.  I tried it, and it did.

My next problem was that the neither the 2.1.5 nor the 2.1.6 install
floppies would recognize my IDE CED-ROM drive, so I would not be able to
install from CD.  However, the Feburary 5th gamma of 2.2 does recognize
my CD-ROM drive, so I thought all was OK, as I would just wait for 2.2.

I then bought a Diamond Speedstar 64 ISA graphics board with 1MB memory,
as the board it came with only did 640x480 16 colors.  Now I seem to have
a new problem.  Although 2.1.5 and 2.1.6 boot up OK with this graphics
board, the 2.2-GAMMA install floppy does not.  After it decompresses the
kernel and goes to execute it, the screen displays complete garbage.

I don't think there is anything wrong with the graphics card, as Windows 95
seems to display OK in all the supported resolutions and number of color
options which are supposed to work with a 1MG graphics card.

My Pentium system, however, which also has a Cirrus S3 based accelerated
graphics card with 1MB memory boots from the 2.2-GAMMA install floppy
just fine.

Any ideas?
