Hi Yukin,
Im looking for the same thing and started a thread out here: http://www.vintage-computer.com/vcforum/showt … -286-setup-disk
As you can see we already put a lot of effort into it to find it.

So If possible we could join forces to search for a copy of this disk.

Stay Tuned!

Hi Yukin,

Finally got it.

1) Create a DOS boot floppy
2) Download GSETUP (version 3.0 2/88) here http://ibm-pc.org/utilities/system/GSETUP.zip . Note that other versions of GSETUP do not work!
3) Extract the file "GSETUP.EXE" to the root of the DOS boot floppy
4) Start your Epson Equity LT 286 with the DOS boot floppy
5) Execute GSETUP (might look a bit scrambled due to the wrong screen resolution)

Within GSETUP:
1) Choose "[1] Setup CMOS RAM Parameters"
2) Edit the following parameters:

1   [0] Date: -
2   [1] Time: -
3   [2] Floppy Disk A: DS/HD 1.44m 3 1/2"
4   [3] Floppy Disk B: Not installed
5   [4] Hard Disk 1 (C:): Type 2
6   [5] Hard Disk 2 (D:): Not installed
7   [6] Base Memory: 640k
8   [7] Expansion Memory: System dependent
9   [8] Math Coprocessor: System dependent
10   [9] Primary Display: Color/80

3) Press "escape" and choose "[4] Exit" to reboot your Laptop.
4) Enjoy

Kind Regards,
Ruben Geurts

Awesome that you replied with the solution to such an old thread! Big like.

I know I am late and that this thread is almost as ancient as this laptop, but I recently aquired the same and it came with the original disks. Googling for details about the device, I always come across this thread in the top results, so finally let me add a copy of the original reference disk and setup disks with EMM drivers which I uploaded to web archive: https://archive.org/details/epson-disk-images
