Trivial Solutions The LoseThos 64-bit PC Operating System Download LoseThos V7.03 (5.77 Meg) Burn a CD and boot it. It's Free!Long mode on x86_64 computers has eight additional general purpose registers and all 16 of the registers are 64-bit in size. LoseThos runs in long mode and uses 64-bit pointers. With LoseThos, all tasks on all cores can directly access all RAM memory at all times with no banking, protections or segmentation. Essentially, in LoseThos there are no virtual addresses, just physical, because PAGING IS NOT UTILIZED.LoseThos is like nothing else -- I wrote all of it, entirely from scratch, including the compiler/assembler. We're not in Kansas any longer -- I changed the language. See Language Differences from C/C++. No point doing an operating system if it's not different and better.Your assumption is that LoseThos is for pathetic hardware because of the graphics? Nope, it requires a minimum of, like, a x86_64 2.0 Ghz CPU. It's the best you can do without GPU acceleration. See LoseThos Graphics. Emulators are like running on pathetic hardware, so run it directly or use VMWare. It's not very power efficient for laptops, either.I can't be in the business of having different drivers for the same class of device. LoseThos sticks to reasonably common hardware for 64-bit or better machines. Since GPU's vary, LoseThos has no GPU acceleration. This article explains that a GPU is much faster than a CPU. Non-GPU graphics are too slow for high resolutions, so LoseThos will always be 640x480x 16 color. (It takes 1/37th as much CPU power for 640x480x4bit compared to 1600x1200x24bit.)This is not a amateur operating system. I was a paid operating system developer for Ticketmaster at age 20 in 1990 and have worked on this full-time for 7.7 years. Unlike Linux which is, technically, just a kernel, LoseThos includes a complete tool-chain -- 64-bit kernel, 64-bit compiler, assembler, editor, graphics library, document framework and tools such as grep and merge. It never executes code I did not write except a couple BIOS calls during boot. However, it has no networking and with no protections, will crash on bugs or misuse.LoseThos is for recreational programming. I donno, why did consumers buy those kits in the 1970's where you flipped switches to program? With LoseThos, user programmers are a higher priority than developers and simplicity is a priority. So, LoseThos is for a small niche. This is not a group-think understanding of "operating system." LoseThos's simplicity offers something distinct compared to Linux because Linux's code is intimidating. In the case of Linux, the term, "open source" is cruel to amateur programmers.The intended way to use LoseThos is to dual boot on your best machine. LoseThos is all about raw CPU horsepower -- 64-bit, multicored -- making it easy to program without struggling. That's what LoseThos is about.You can dual boot by installing it on a free partition on your main hard drive, but the easiest way to dual boot is to add a second, spare, hard drive; install on that; and use the BIOS to select which hard drive to boot. A FAT32 partition can be used to transfer between operating systems. Make 2 or 3 tiny partitions for LoseThos and, periodically, just copy everything to one of these partitions, making redundant back-ups. The entire LoseThos distribution is only 5 Meg, right?
