Currently my kernel works with

• Raspberry Pi 1 Model B (ARMv6, single-core, 700MHz, 512MB RAM)
• Raspberry Pi 3 Model B (ARMv8, quad-core, 1.2GHz, 1GB RAM)

However it should run on almost all Raspberry Pi boards

U365 supports:

* ATA/ATAPI read/write;
* PS/2 keyboard and mouse;
* VBE 1024x768x32 (by GRUB);
* Up to 4GB of RAM;
* ACPI, but it doesn't work ;
* RTC and PIT;
* WIP preemptive multitasking.

My kernel supports:

Architectures:

• x86 (32 bit)
• ARMv7

Drivers:

• PIT Counter
• PIC Interrupt controller
• PCI Bus
• PCI ATA ( With DMA )
• 16550 UART
• Generic multiboot supplied framebuffer
• PS/2 Keyboard
• PS/2 Mouse
• OMAP3430 General purpose timer
• OMAP3430 Interrupt controller
• OMAP3430 Framebuffer

Which amounts to the following systems: Generic x86 systems, the Nokia N900 and the original Beagleboard.

Obsidian OS supports:
- x86 CPU (32-bit) with SSE2 instructions
- Multiprocessing
- ACPI
- APIC (I/O and timer, no PIC, no PIT)
- SmBIOS
- PCI bus
- PS/2 keyboard and mouse
- Serial-ATA devices (AHCI, no IDE emulation)
- VBE-compatible video card (24-bit and 32-bit modes supported)

Planned support:
- 64-bit version.
- USB (keyboards, mices, sticks...)
- ATAPI devices on AHCI.
- Network cards
- Sounds cards (SB16, AC97)

Currently, I'm in the very early stages, but here's my support design goals:
Architecture:
* x86 (SSE2+)
* x86-64
* ARM - Raspberry Pi
* ARM64 - RPI
I only have the Pi for ARM tests, but if I can do that it should be fairly portable as a whole.

Features:
* AVX support
* AVX-512 support
* Much more to come!

Currently:

* i686 (32-bit) CPU, including x87, MMX, SSE, etc.
* ATA hard drives
* ATAPI optical drives
* PS/2 (compatible) keyboard/mouse
* Up to 4GB RAM (tested 16MB - 4GB)
* VGA (compatible) graphics + VBE support

Planned (near future):

* "Native" (2D framebuffer) support for Intel, AMD, NVidia and "BGA" (Qemu/Bochs/VirtualBox) graphics.
* USB (HID and MSD)
* Possibly PAE for >4GB RAM
* As yet undecided selection of NICs

Seeing as re-writing my driver layer is next on my to-do list, much of this is not fully decided.

Implemented drivers for MollenOS currently are (EHCI is not fully featured yet, no support for transaction translators or isochronous transfers yet):

- AHCI
- ACPICA
- MFS (my own file-system)
- HPET
- USB Stack (OHCI, UHCI, EHCI)
- USB MSD
- USB HID
- (x86) PCI/PCIe
- (x86) CMOS
- (x86) PIT
- (x86) RTC
- (x86) PS2 Mouse & Keyboard
- (x86) APIC
