BIOS parameters & hardwares choices :

Icaros should work on most computers in VESA modes, but it is sloooow. Anyway, SATA operations must be modified in BIOS and USB3 won’t work.

You must choose / build a computer in taking care of the hardware compatibilty.

Personnally I have : GMA945 in an old Dell optiplex GX520 Desktop, A DELL Optiplex 755 with an nvidia Quadro380, Soundblaster Audigy II, network RTL8169.

I do not recommend nvidia GeForce 980 “like” gfx cards they are too hot !

You already have your computer ? Niiiiiice !

In BIOS modify the SATA operation to


or to


I have an old 80Gb 5400rpm SATA disk. Don’t forget icaros can’t manage disks that are bigger than 120Gb.

Install choices :

Wipe disk

I do this the first time. It creates a new Partition table. You must have chosen the right size for SYS: and WORK: no choice needed. Personnally, I think 8Gb for SYS is quite enough.

After the reboot, when you launch “install Aros” again :

  • make a full install on SYS only, then change Myworkspace: assigns manually, cause there are sometimes issues on assigns if you choose to “Use Work: partition” but don’t “Format” it.

GRUB parameters :

According to this thread : http://aros-exec.org/modules/newbb/viewtopic.php?topic_id=8937&forum=24

the ata.device and ahci.device (ata and ahci/sata native devices) don’t work properly and certainly will crash for most users.

To get rid of this you must edit “SYS:Arc/pc/grub/grub.cfg” file and replace the line

module /Devs/ata.device


module /Devs/alt/ata.device

to load the alternative ata device.

Delete the line

modules /Devs/ahci.device

modify the first line replacing




save and reboot. All should be fine now.
