This is a very small computer, but very powerful for its age, and it was really fun to play with.
Due to the twisted configuration of the D-Link DE-650 on Windows for Workgroups 3.11, I cleared the system and installed Windows 95. I used OSR1 because of its smaller size, about 40MB.
The great challenge (and fun part) was to find a floppy version of Windows 95 OSR, and add the kit on 21 Floppy disks. Of course, I could have done this many different ways, but decided to install Windows the old classic way.
After a few hours of writing floppies, printing labels (because I’m never writing 21 floppies in a row ever again) I’ve installed Windows without any issues. Photos of the floppies and installation progress are in the gallery.
I’ve also installed some software on it, but the most interesting part was the ability to install the cygwin linux subsystem, which allowed me to install a web server and an irc server, which were up 24/7 for several months.
However, due to its age and the prolonged uptime of the computer, the battery got a bit swollen and died. Because of the design of the power circuit, the computer cannot be started without the battery (the AC jack plugs in directly to the battery), so I need to get the battery cells replaced in order to start the computer again and write a bit more about the software part of it (which is on my to-do list for over 2 years)

Interrupt requests (IRQ) are used by hardware devices to signal to the motherboard that a request must be fulfilled.
IRQ 0 is used by the system timer.
IRQ 1 is used by the keyboard controller.
IRQ 2 is used by the second IRQ controller.
IRQ 3 is available with BIOS 1.24 or later. IRQ 3 is commonly used by modem PC Cards.
IRQ 4 is used by the serial port.
IRQ 5 is available.
IRQ 6 is used by the floppy disk drive controller.
IRQ 7 is used by the parallel port.
IRQ 8 is used by the real time clock.
IRQ 9 is available.
IRQ 10 is available unless CardSoft is installed. If CardSoft is installed, the IRQ is used as the card status change interrupt for CardSoft.
IRQ 11 is available. It is commonly used by network PC Cards.
IRQ 12 is used by the EZ-point mouse or a external PS/2 mouse.
IRQ 13 is used by math coprocessor.
IRQ 14 is used by the hard disk controller.
IRQ 15 is available.
