Technical information

---

This page describes the hardware and software information for this year's EGOI.

Hardware

The contest will be held on HP ProBook 4 G1iR 16 inch laptops with US keyboard layout.

We will not provide external keyboards to contestants that do not bring their own. However, we will provide an external mouse.

• Display: 1920x1200
• CPU: Intel(R) Core(TM) 5 120U
• Memory: 24GB DDR5

We provide here photos of the keyboard, mouse and side views of the laptop.

Important : the laptop built-in keyboards are US ANSI. ANSI keyboards do not have a key that many national layouts use. Please make sure to bring your own keyboards if ANSI keyboards are not a good fit for your preferred layouts.

Requirements for external keyboards

If you wish to bring your own external keyboard (or mouse), it must not be programmable and not have any wireless functionality. This matches IOI rules.

On the last point, we remark that keyboards that have wireless functionality, but are connected with a wire, are not allowed .

For the purposes of this rule, a keyboard is considered programmable if the behaviour of its keys can be configured in a way that persists when unplugging and re-plugging the keyboard.

External keyboard submission process

In line with contest rules, external keyboards must be submitted at the practice session, and left in the contest hall at the end of the session and at the end of Day 1.

The Technical Committee will examine the keyboards and determine whether they comply with the above rules, and inform team leaders if not.

The final authority on whether a keyboard is allowed rests solely with the Technical Committee.

Important : last year, we made an exception to the "programmable" part of the rule due to a large number of programmable keyboards. Thus, we invite team leaders to check carefully their contestants' keyboards. If in doubt, you can send an email to info@egoi2026.it with the keyboard model and pictures, so that we can check them in advance.

Software

The competition will run natively on the laptops on Linux. For online contestants a VM with very similar settings will be provided.
