Hi everyone,
Today , I would like to introduce my OS , its name is Genius HorizonOS (GHOS) .
At the first here is some screen shots :



GHOS is a closed source protected mode OS and it has many features like :

• FAT12 Read only file system for floppy. [very old, i know ]
• Multitasking.
• Genius Horizon Executable (GHX) : a new executable format designed especially for GHOS.
• The whole OS and applications are in kernel mode , so you are free to do all kernel mode instructions in your applications (for now ).
• Errors handler , but no debug data .
• Easy API for application development. [ no support for keyboard API right now ]
• minimal ACPI support.
• CTRL + Enter to return to the CLI from a hanging APP.

Requirements :

• 16 MB of RAM [17MB for VPC].
• Intel Pentium IV CPU and later, or AMD Athlon and later.
• Floppy disk.
• ACPI based PC for ACPI features.
• PS/2 Keyboard or emulated USB keyboard.

The OS was tested on Qemu, Bochs, VPC and some real hardwares (with some problems in ACPI ).

I hope you got interested in my OS ,and any feedback is appreciated.

here is a floppy disk image and a small demo APP for developers with API datasheet :

In the name of the gods, Tyrion Lannister, Kanye West, and the god of AD carry mechanics Doublelift, peace be upon you too brother.

I tried to run it in Qemu with qemu -fda GHOS\ V0.0.5\ Alpha\ -\ 4.IMG -serial stdio -m 32 and it pagefaulted.

Hi piranha,
I am using this command line "in windows" and it works perfect on my side.

Can't seem to get it to boot past the panic screen. What version of qemu are you using?

I get a panic on boot in VMM Init on VMware Workstation 8.0.3 (the VM has 32 MB of RAM).

Attached a screenshot.

I'm on 1.0.1. I got it to boot up in bochs, but the first three times I tried to load the demo app it just rebooted (TF'd?). But the 4th time it worked properly, and I was unable to reproduce the reboot bug. I get the same error as pcmattman only if I make the memory size something like 4000MB.

Hi,
I really surprised from the results
anyway : the "VMM Init Failed" happens because that the OS can't get the BIOS Memory Map , and the restart is a triple fault.
I hope someone else test the OS to see if this error happens again or it is a special case.
[My problem now that i can't produce that bugs here for debugging]
[Note : The website in the panic screen is down ]

Appears to work fine in VirtualBox here. Fails to shutdown the system but displays that it is safe to turn off the computer instead. No crashes.
