AND (Virtual) Hard Drive Geometry
As soon as I heard the familiar tick of a Memory Check from PCem 0.7 that's
when I knew that I had HIT THE JACKPOT!
Man hug for Tom!
Many other people have expressed Thanks for PCem so much better though!
This is just one more Thanks++.
I don't cry, yet there was certainly water coming from one (maybe both) of my eyes(?)
when I first booted a familiar old (yet, virtual) 386/25 with the tired old AMI BIOS.
Is there some way to send some digital money (paypal bitcoin or silver) to you, Tom?

In any event, after finding the rest of the ROMS etc... PCem is a blast!

(Virtual) Hard Drive Geometry
I haven't found an easy / automated way to recreate virtual hard disk drives
that existed back in the late 1980's and early 1990's : Connor Maxtor Seagate.
So...
FWIW: The creation of small / tiny hard drives dating back to the big hair;
power ballad era has become something of a mini-project for me.
Since I can't seem to find a comprehensive list of Hard Drive Geometry
among Google.com or Startpage.com etc.; I have created a brief listing of
hard drive geometries from as many BIOS as I could find without wasting
too much time and effort. In less time than it takes to watch some adorable
kittens in a youtube video, I threw together, in my opinion, a decent listing.
Until I can incorporate these into a semi automated script I'll use the values
below to manually create (and virtually) 'pull a NEW Conner hard drive from a box.'
But then, Isn't faithfully recreating the hardware the driving spirit behind all
emulators? I hope some others find these Hard Drive Geometry tables useful...
