AHCI and Virtualbox
Paul Smedley:
Hey Ian,
--- Quote from: Ian Manners on March 29, 2023, 04:45:14 am ---Thought I would update to AHCI from IDE drivers/controller as well reading this thread but I have been unsuccessful.
I added BASEDEV=OS2AHCI.ADD to my Arca config.sys but the container stops booting, just displays the Arca boot screen, no error message, and does not progress any further even I leave it 30 minutes.
I'm using Virtualbox Version 6.1.40 r154048 (Qt5.12.8) [Stable channel] under Ubuntu.
Version 7.x of Virtualbox is not listed as Stable, I did try upgrading to it a while ago and very quicky reverted back to 6.1.40.x due to wierd stuff, so will stick to the stable channel from now on.

Interesting... I was able to 'see' an AHCI controller and blank image from the AOS boot ISO - I did have to enable AHCI in the pre-boot menu though.
Paul Smedley:
Update on this - AHCI works on Virtualbox with a single core - but not with multiple cores. adding /MAXCPU=1 allows the use of AHCI.

A better workaround, is to use 3 cores in Virtualbox, rather than 4.
With 4 cores I get the error, with 3 cores, the system boots fine. The host system has 4 cores.
Ian B Manners:
Thanks for that insight Paul :)
I've been letting VirtualBox use all 12 cores, think I'll try it with one core as it's really just for PMMail anyway.
Added: Adding /MAXCPU=1 in the config.sys works, where as letting VirtualBox only use 1 CPU does not. Thanks Paul :)

Hi
VirtualBox 7.0.8 (Windows/Linux host) was released on April 18.
I don't see anything related to storage in the Changelog. It will be good to see if there are some changes with ArcaOS.
Regards
