reinstall grub 2 in IcAROS

Reinstall grub2 if stuffs go wrong :


I had a problem this morning when booting my machine. Screen stayed blank at the first step of the boot, instead of displaying the grub screen. This comes from the dma on my computer. So I disabled dma with “nodma” option in grub, now. I don’t have anymore problems.

So, here is the way if your system don’t boot up in case of a messed up grub.

Test your hardrive is still ok, booting with an installation DVD or pendrive.

If the hard drive still appears in wanderer, so it’s is certainly you did something wrong with your grub.

Aros comes with a nice little utility that allows us to reinstall the grub : http://aros.sourceforge.net/documentation/users/shell/install-grub2-i386-pc.php

First we have to know the device and the unit of your hard drive. Right click on the icon and get to “Informations”. Here are the device and the unit. For me it is : ata.device unit 4.

Open a shell window, and type (change device and unit so it fits your system config) :

for regular icaros (and previous) :

install-grub2-i386-pc DEVICE=ata.device UNIT=4 GRUB=DH0:boot/grub

for icaros 1.5.2 WIP5 (and future releases) :

install-grub2-i386-pc DEVICE=ata.device UNIT=4 GRUB=DH0:Arch/pc/grub


Restart, stuffs should have been resolved.


mount an ISO file in IcAROS

So you have an ISO file and want to access it without having to burn a DVD ?

Here is what you have to do :

– copy the file (iso) to the drawer “AROS:Diskimages”

– rename it as Unit0

– add this into the file AROS:Devs/Mountlist

FileSystem = cdrom.handler
Device = fdsk.device
Unit           = 0
LowCyl         = 0
HighCyl        = 0
Surfaces       = 1
BlocksPerTrack = 1
DOSType        = 0x41434400
Activate       = 1

– open a shell window and type :

mount ISO:

In regular IcAROS, the device doesn’t show up in Wanderer, but you can access it using “ISO:” in a shell, or in DOpus.


icaros tutorial

This article is there to help you understanding how to install / update the last official IcAROS release : IcAROS 1.5.2 WIP5, what it is made of, what you have to expect of it, and some workarounds on some issues.

I am very happy to have downloaded it, and even if some stuffs don’t work like a charm, I’m aware of that : it is a VERY GREAT improvement, smooth and reactive.

Don’t forget : AROS is 100% open source, it means that you can participate, and it NEEDS your help !


What is IcAROS 1.5.2 WIP 5 ?


The “WIP” in the name means “Work In Progress”. This is the last official download available to users until the next official IcAROS release is made.

This is an improved version of IcAROS 1.5.2, because it uses the last abi-v0-ot branches of AROS i386 (see below). But in the same time, you shouldn’t mix the WIP5 files with the old and reinstall from scrash.

What it is made of ?

This version includes DOpus, and works on ABI-v0-ot core files of AROS i386.

ABI-V0-ot WTF is it ?

Usually, AROS counts 2 main development branches that are not binary compatible : ABI-v0 and ABI-v1.

ABI-v0 is the official core to use on your native installation, or you linux hosted. It is compatible with the programs released on AROS-ARCHIVES, and most of the time you would use it to update your installation (have a look to this article)

ABI-v1 is a more experimental branche of the development, that is not binary compatible with the rest of the programs we know in usual AROS distros. This is a development branch, where developers try stuffs, improve, break other stuffs… it is a “use it at your own risk” branch. From time to time, improvements from ABIv1 are “back ported” to ABI-v0, and include in it, so the world is happy to have a better core.

Now, we have the ABI-v0-ot (OT means “on trunck”), where deadwood is including (he works on this for one year now) all the best stuffs of ABIv1. This is the branch used by IcAROS 1.5.2 WIP5. This branch has been done to be 100% compatible with all the available programs. The last builds include the new, and very fast, tlsf memory manager.

What do I have to expect from IcAROS WIP5 ? Continue reading “icaros tutorial”

install dopus on regular IcAROS

Introduction :


Yepa, that’s fantastic : DOpus 5.9 has finally been released, 15 years after the 5.89.


That’s really fantastic, and I can hear the sounds of many people saying, I want it running on my IcAros !

There are two main ways to get DOpus running on IcAROS :

Install DOpus package on the official IcAROS, and update core files : this is what I do in this article

– or Install IcAROS 1.5.2 WIP5 : WIP5 tuto there.

Both ways have good and bad points :

OWB problem with the SSL CA cert on IcAROS

What versions ?

This article is about those software versions :

– Odyssey Web Browser (OWB) v 1.16.2

– IcAROS 1.5.2-2

Your question can be :

I have problem surfing in https with OWB. It says that he has a problem with the SSL CA certificate.

This can be an error 60 :

Unable to connect to "https://www.facebook.com"
Error 60 : Peer certificate cannot be authenticated with known CA certificates

or maybe an error 77, like this :

Unable to open https://www.facebook.com/....
Error 77 : Problem with the SSL CA cert (path? access rights?).

Possible workarounds :

share over the network between IcAROS and Ubuntu

Introduction :

Sharing files over the network is something like an obligation nowadays.

I personnally don’t like Windows, so I won’t speak about this side. I prefer the dark side : linux, especially ubuntu (here 12.04LTS). Anyway, samba is samba, so it should work with every linux distrib.

As we speak about computering @home, we will stay in a VERY SIMPLE config.

So, we have for this example :

– One machine running IcAros 1.5.2-2

– One machine running Ubuntu 12.04LTS

– let’s assume the ubuntu samba server is called “HADES”,

– in a WORKGROUP  called “PHLEGETON”,

– with the IP adress, let’s assume it is “192.168.173“. Ofcourse, you must change this to fit your ones.

– let’s assume the path to share is “/media/data”

– let’s assume the share name will be “styx”

We also have a local user. Let’s assume it is “jess”. Continue reading “share over the network between IcAROS and Ubuntu”

my IcAROS /boot/grub/grub.cfg file (only icaros before 1.5.2)

I gives this to you to explain how you can play with graphical modes (cf this post) and switch between VESA and NATIVE modes under IcAROS.

The first menu entry is begining at the line menuentry “Icaros Desktop”. The first entry in the list is the one that will be used by default.

There is no driver given in the command line (no “nouveau.hidd” or VESA appearing), so it takes the last config saved inside IcAROS. If you want to be sure to boot in VESA mode your have to write down something like “vesa=1600×1200@60” in the boot line.

You can change the background image with the “background_image” option. Why isn’t it as simple in linux ?

playing with graphical modes inside IcAROS (VESA/native nouveau.hidd)


VESA is perfect for compatibility with ALL the gfx cards. For more informations about VESA : http://en.wikipedia.org/wiki/VESA

But it is slow, and Warp 3D is badly supported.

Also, you can have problems changing graphical modes (need to restart the comp’), or even finding a mode that fits your needs and your screen (for me, I had issues with my wide 22′ monitor)

To know the list of VESA modes supported by the graphic card, on the grub screen type “c” to get into the “grub command line”, then type : Continue reading “playing with graphical modes inside IcAROS (VESA/native nouveau.hidd)”
