Roadmap for Arca Noae Product Development
Arca Noae is continually working on support for new drivers for new hardware and applications with its business partners and developers. These are some of the projects we are currently working on.
Short Term Projects (Less than 3 Months)
These are projects which are currenly under active development. Completion of these projects is expected fairly soon.
Enhanced printer support with CUPS for OS/2
A new CUPS printer driver package as part of Arca Noae products (link here to subscription, when available). This package will come with an updated Postscript printer for OS/2 that will make CUPS printers function better under OS/2. The CUPS printers drivers will allow OS/2 to support many modern Inkjet and Laser printers.
New Ethernet and Wireless network drivers
With the aid of the MultiMac framework Arca Noae already provides support for some Intel, Nvidia, and Realtek chipsets based on Linux drivers. Changes in the Linux driver architecture have made maintaining these drivers and porting new drivers increasingly difficult. As was announced at Warpstock 2014, Arca Noae is working on a alternative new library for porting FreeBSD drivers to OS/2. Initially we expect several new ethernet drivers to be produced by this new approach. Wireless drivers will follow after the first few ethernet drivers, but may take a bit longer due to the increased complexity of wireless drivers.
Medium Term Projects (Less than 1 Year)
Updates to the UNIAUD audio driver
OS/2 has been using the UNIAUD audio driver to support audio cards and audio chipsets on mainboards for years. The driver is currently undergoing a major update to make it much easier to synchronize the OS/2 sources with the Linux ALSA sources. This will enable Arca Noae to provide updates and support for more audio chipsets more quickly. New UNIAUD updates will be available via the Arca Noae support product.
Long Term Projects
USB 3.0 host controller support
We are investigating what changes will be necessary for the current USB stack to support a USB 3.0 HC driver.
Support hard discs larger than 2 terabytes
Currently OS/2 supports hard disks up to 2 Terabytes. Several possible solutions for larger disks are being investigated.
Support for booting OS/2 from hard disks with a GPT partition layout
The MBR support in the BIOS has been replaced by the GPT disc layout which is part of the UEFI standard. Current research seems to indicate that we can provide GPT support via something called a hybrid MBR.
