wwiv 5.4 qemu door example (experimental)

• So here is a basic setup that's gotten me close. It still doesn't quite work because either the display is funky (the ANSI characters are not cleanly being handled, especially for screen clears) or the user input is super slow in responding, or there's too much extra input streaming through (like when the sgabios device is used).

Hopefully someone else will have some better luck, and this may very well work for someone else's door; TW2002 may just be hosed.

install qemu-system-x86

	aptitude install qemu-system-x86

create disk image

	https://en.wikibooks.org/wiki/QEMU/FreeDOS
	qemu-img create -f raw freedos.img 100M

Download and Install FreeDOS

	wget http://www.freedos.org/download/download/FD12CD.iso
	qemu-system-i386 -localtime freedos.img -cdrom FD12CD.iso -boot d -curses
	Install to harddisk
	Language
	Yes - Continue with install
	Partition C:
		Large Disk support: NO (our OS disk is only 100MB)
		Create Primary DOS partition
	Reboot
	Install to harddisk
	Language
	Erase and Format
	Keyboard Layout
	Base packages only
	yes- Install (wait)
	return to DOS
	shutdown

install the sgabios display device sudo apt-get install sgabios

Set up fdconfig.sys and autoexec.bat

For editing the fdconfig.sys and autoexec.bat, I HIGHLY recommend mounting the image file locally. It's a LOT easier to use vim, nano, whatever than it is to try to use freeDOS' editor

to mount directly, as root:

 mount -t msdos -o loop,offset=32256 freedos.img  /media
 vim /media/fdconfig.sys
 vim /media/autoexec.bat
 umount /media

Set up your Doors directory inside the qemu image Use the DPMI version of TW2002 We can either copy the file into the qemu image, or make it available using the fat:rw:/directory

to mount directly, as root:

mount -t msdos -o loop,offset=32256 freedos.img  /media
then copy in the 2002V309-DPMI.ZIP to /media
then umount /media

To put in a directory and mount inside of qemu as a fat volume make a /tmp/tw2002 directory, then boot your VM this will put /tmp/tw2002 as D: inside the VM

TERM=linux qemu-system-i386 -localtime freedos.img -hdb fat:ro:/tmp/tw2002 -parallel none -serial none -curses
