This operating system uses standard operating system concepts used in the 32 bit environment. It will eventually be ported to 64 bit including IA64. This ClassicOS operating system, aims to support major hardware and software technology existing from when the first 32 bit systems appeared on the market through the early 2000's and most of those have been listed below.
This project uses the C library and Assembly language.
GNU Make 4.2.1 CMake 3.13.4 GNU 8.3.0 gcc (Debian 8.3.0-6) 8.3.0 nasm 2.14 GNU ld (GNU Binutils for Debian) 2.31.1 binutils
For testing, QEMU i386 and TigerVNC/VNCViewer on ::1:5900
This project will use MIT or the GPL license and will be fully open source.
Ideal situations aside, My goal has always been:
1-2 person working on bootloader 1-2 person working on kernel 1-2 person working on drivers 1-2 person working on issues/bugs 1-2 people working on applications/user-space 1-2 people working on Networking 1-2 people working on memory issues, stack issues, etc.
at least one person doing hardware and software testing and writing tests in a test framework
At least one major bug fix a week At least one minor buf fix a week At least one new feature a month (or more)
This project initially aims to support all 32 bit Intel and AMD processors Including;
-- Intel -- i386 SX and DX Processors i486 SX and DX Processors Pentium Processors (60 to 120MHz) Pentium Pro Processors Pentium II Processors Pentium II Xeon Processors Pentium III Processors Pentium III Xeon Processors early Pentium 4 Processors (Willamette, Prescott, Northwood)

Might eventually support GRUB/GRUB2 and/or UEFI/EFI.
Include support for AHCI and ACPI
ISA EISA VESA/VESA Local Bus (VLB) PCI PCI-X PCIe 1.0, 1.1, 2.0 AGP DIN 41416/NuBUS
This OS aims to support major hardware existing from 1985 to early 2k's.
