Experimental OS. LoseThos is a 64-bit, multicored, multitasking, open source, public domain, ring-0-only, single-address-map operating system for the IBM PC. It requires a 64-bit x86_64 CPU and 512+ Megs of RAM. It does not have GPU acceleration, so I limit it to 640x480 16 color graphics. LoseThos will run natively, either stand-alone or dual booted. The easiest way to dual boot is to install on a 2nd hard drive and select which to boot with the BIOS. Use LoseThos' installer to install onto a partition. LoseThos has an optional master-boot-record boot-loader and can partition a drive if necessary. YOU CAN'T COMPILE WITH OTHER COMPILERS. Use InstallBoot() to make, if you like. The vision for LoseThos is a 64-bit Commodore 64 that's a thousand times faster than the original and has a shell that is C/C++ instead of BASIC. It's for recreational programming. The reason you would pick LoseThos over Linux is that it is only 129,242 lines of code, so you can easily tinkering. LoseThos isa secondary operating system you will use in additional to Windows or Linux because LoseThos does not have networking .....(free).....
