How to Set Up ttylinux
under the Bochs Emulator


Copyright©2013 by Daniel B. Sedory


If you have not yet done so, please install the Bochs Emulator under your OS Platform. Although most of the following will apply only to those using Microsoft® Windows™, some of this page will also be useful to those running a Linux distribution as well. To install Bochs, please see our How to Set Up and Run the Bochs Emulator page with dlxlinux, and be sure to download the ttylinux-virtio_i486-16.1.iso.gz file from the ttylinux web site.

The following assumes you already have BOCHS installed on your PC, and know how to navigate to its install location. On a Windows™ PC, this should be: "C:\Program Files\Bochs-2.6.2\" (or whatever current version of Bochs is installed as the folder name). Let's begin:

========================================================================

Do you want to create a floppy disk image or a hard disk image?
Please type hd or fd. [hd]  Press ENTER key!

What kind of image should I create?
Please type flat, sparse or growing. [flat]  Press ENTER key!

Enter the hard disk size in megabytes, between 1 and 8257535
[10] 180  Type 180, then press ENTER key!

I will create a 'flat' hard disk image with
  cyl=365
  heads=16
  sectors per track=63
  total sectors=367920
  total size=179.65 megabytes

What should I name the image?
[c.img] hda.img  Type hda.img, then press ENTER key!

Writing: [] Done.

I wrote 188375040 bytes to hda.img.

The following line should appear in your bochsrc:
  ata0-master: type=disk, path="hda.img", mode=flat, cylinders=365,
 heads=16, spt=63
(The line is stored in your windows clipboard, use CTRL-V to paste)

Press any key to continue

Please type 0.16, 0.18, 0.32, 0.36, 0.72, 1.2, 1.44, 1.68, 1.72, or 2.88.
 [1.44]  Press ENTER key!
I will create a floppy image with
  cyl=80
  heads=2
  sectors per track=18
  total sectors=2880
  total bytes=1474560

What should I name the image?
[a.img]  Press ENTER key! (Change to b.img 2nd time through.)

Writing: [] Done.

I wrote 1474560 bytes to a.img.

The following line should appear in your bochsrc:
  floppya: image="a.img", status=inserted
