OS/2 compatible hardware

2020-01-22 01:49:15 -- Eugene Gorbunoff [os2.guru]

OS/2 GURU published more reports about tested hardware

  • modern motherboards
  • USB Audio adapters
Database of hardware: http://os2.guru/hardware.php

What computer configuration is optimal for OS/2 in 2020?

  • you don't need extreme NVidia video adapter
  • no need in i9 and 64 Gb of RAM
  • on the other side, it's stupid to run OS/2 on MMX and Pentium from 2004

OS/2 Benchmarks: http://os2.guru/sysbench

Tested hardware

2020-01-05 03:18:08 -- Eugene Gorbunoff [os2.guru]

os2.guru makes efforts to update the database of hardware tested with OS/2. We could publish a hundred of reports during the january. Send us report about modern hardware manufactured after 2010.

What computer is better for OS/2 ?

2020-01-04 01:44:17 -- Eugene Gorbunoff [os2.guru]

We are collecting benchmark logs at http://os2.guru/sysbench

Let's analyze the results,

  • No need to use expensive external video adapters. Better use Intel integrated than NVidia external.
  • (obviously) 4 cores is better than 2 cores
  • (obviously) SSD is faster than HDD
  • (obviously) New computers are faster than old

Let's collect other 30 reports to get more conclusions.

What computer is faster in OS/2?

2019-12-15 23:14:50 -- Eugene Gorbunoff [os2.guru]

The user have many questions:

  • If you should assemble super fast computer, is it necessary select the best CPU?
  • What configuration is weak and slow in OS/2?
  • What computer is good, doesn't freeze?
  • Is it necessary buy the latest i7? or you can stay with Core 2 Duo?

Let's collect reports generated by sysbench and make conclusions based on the statistics.

If you want play the game:

  • Download sysbench
  • start sysbench, select: All tests
  • Wait (5 - 10 minutes), don't start apps
  • save the report to 20191225.txt
  • send the report and notes to email: eg at ecomstation dot ru
  • Please add:
  • a) Model of motherboard / laptop / brand PC
  • b) CPU? how many cores do you see at Pulse?
  • b) Model of video card, what driver: SNAP or Panorama?
  • d) model of HDD / SSD:

We will collect the results at the site: os2.guru/sysbench

Core 2 Duo modernization to Xeon

2019-12-14 01:51:09 -- Eugene Gorbunoff [os2.guru]

We can't recall if OS/2 users were discussing upgrade of Core 2 Duo to Xeon processors. Installation of Xeon LGA771 to LGA775 socket. Seems that this topic was popular in the Internet since 2014.

Imagine that you upgrade CPU with 2 cores and cache 2 Mb to *servre* CPU with 4 cores and 12 Mb cache. Of course, your computer should work faster. Check Xeon E5430

So, reminder: If you have motherboard with Core 2 Duo (LGA775), with support of 1333, 1600, then you can install Quad Xeon CPU (LGA771). Of course, you should make some efforts: update bios from CD + cut the socket + attach small converter to cpu.

ATTENTION: Send us the comparison: Before and After

  • use sysbench. collect All tests before and After upgrade

Write a review of OS/2

2019-12-11 16:57:10 -- Eugene Gorbunoff [os2.guru]

OS2.GURU is interested publish installation of OS/2 on unique computer.

example: mini-itx с wifi (rus)

We expect that you show interesting computer:

  • all-in-one computer with IPS screen
  • Thinkpad X201 with IPS display
  • new cheap laptop from a shop with UEFI
  • Thinkpad W540 or other expensive
  • Thinkpad T61 Frankenpad or Z61t
  • mini-ITX с wifi motherboard
  • industrial computer with mini-itx
  • Acer 8930G 18"
  • etc

The review seems finished if you describe how it will be used (review of installed applications)

eCo Software can reward some reviews. (virtual 5$, 10$, 15$ which you can spend to purchase our apps)

ArcaOS (OS/2) - a road to audio-nirvana

2018-11-24 02:33:18 -- Eugene Gorbunoff [os2.guru]

We found a discussuon of ArcaOS (OS/2) for audiophiles at DAstereo.ru site. Discussion (RUS)

(you need a modern web-browser to open this site)

OS/2 and 4K monitors

2018-08-06 11:07:14 -- Eugene Gorbunoff [os2.guru, Igor Sapegin]

ArcaOS 5.0 + Panorama videodriver support 4K monitors:

  • use video adapter with support of 4K
  • the video mode works if connect via DisplayPort, HDMI - doesn't


Now the user should solve the problem of small letters and icons.

OS/2 and AF / Advanced Format

2017-03-13 04:02:09 -- Eugene Gorbunoff [os2.guru]

Help us find the discussion of AF standard for harddrives support in OS/2. There was a discussion somewhere in the Internet, maybe at os2world.com

General questions: can you install OS/2 to AF disk? Do you feel slow speed? How to create partitions to follow AF standard?
