How do I install this on 86box or PCem? ClassicMacOSGuy1067 (talk) 03:39, 8 December 2022 (UTC)

This manual is assuming that you are using the 3.5" floppy version. The reference disk is available here.

1. Create a 86Box virtual machine:

86Box Configuration

Floppy & CD-ROM drives	Floppy drive(s): One 3.5" 1.44 MB drive CD-ROM drive(s): None
Notes
You will need a IBM PS/2 model 80 reference disk to configure the system. After booting into the reference disk, It is recommended to partition and format the hard disk in MS-DOS.

2. Boot into the reference disk. After automatic configuration is complete, reboot again into the disk and set date and time.

3. Boot into a MS-DOS disk to partition and format the disk with fdisk and format.

4. Boot into the install disk. After booting, exit setup by pressing the Esc key and type in:

ren disk01.sys disk01.bak
copy disk01.esd disk01.sys

and reboot into the floppy again. Then, continue as usual. If then prompted to format the disk, answer "NO".
