We have identified and corrected an issue in our production build system affecting the ArcaOS 5.0.3 ISO resulting in missing USB driver files normally loaded when booting from DVD.
If you normally install from USB flash drive or directly from the ISO you do not require this fix to install.
If, however, you normally install from DVD or from the ISO into a virtual machine which requires USB keyboard and/or mouse emulation, this fix is required in order to load the USB stack for the installation process.
The ending installation is exactly the same, with or without this fix, as no changes to anything installed to the local drive(s) have been made. This is only for the purpose of booting from the installation DVD and navigating through the installer.
Unfortunately, this fix requires a full download of a fresh ISO, as there is no practical way of inserting this small fix in an existing ISO or DVD. As a result, all currently cached ISOs here have been expired. At your convenience, please log into your customer portal, access your ArcaOS order from the Orders & Subscriptions page, and request a fresh ISO.
We apologize for any inconvenience this issue has caused, and thank you very much for your patience. Thanks also to those who reported the issue to us.
