NT-kernel on PSP

ardatan · Post by **ardatan** » Wed Feb 06, 2008 11:58 pm

Hi everyone,
ReactOS is open source based on NT Kernel operating system.
Slim can run this OS. ReactOS's System Requirements are:
* 32 MB RAM
* IDE hard disk of at least 150 MB
* FAT16/FAT32 boot partition
* 2 MB VGA graphics adapter (4 MB recommended)
* CD-ROM drive
* Standard keyboard
* PS/2 compatible mouse or Microsoft Mouse-compatible serial mouse

Can we build this for PSP with mips toolchain and can we boot kernel with uClinux on PSP's boot loader?

Hi ardatan,

do you mean you are interested in running XP application on your PSP?

ardatan · Post by **ardatan** » Thu Feb 07, 2008 1:42 am

yes, i mean.
reactos is like wine. which toolchain should i use? Or can mipsel-linux toolchain build that? Not only XP. We know NT 5.0 as XP or 2000.
ReactOS has NT(XP,2000,Vista) subsystem.

ReactOS can run x86 exe applications. It emulates Windows binaries.

I don't see MIPS listed there, sorry mate.

I saw that Windows NT 4.0 ran at MIPS arch.

Windows CE was distributed for MIPS, the screen (at least on my old cassiopeia) was roughly the same as the PSPs even :D

That simply won't work because ReactOS is just an Operating System, not a x86 emulator, and Windows programs are compiled for x86, not MIPS. So that means you'd have to rebuild from source, and if you want Windows-only programs, that's probably not possible :)

I know. I want to say ReactOS is NT Kernel. I don't want to build x86 emulator. We can create MIPS-NT programs. Win32 gui can use as GUI not SDL. For example Bochs......

The last time I checked, ReactOS had a LOT of x86 assembly language written specifically toward the PC for things like interrupts and timing and misc hardware. It would take a lot of work to make ReactOS work on another processor or hardware platform.

what J.F said and it'll take forever to port.

at
http://en.wikipedia.org/wiki/MIPS_architecture
you can find

Among the manufacturers which have made computer workstation systems using MIPS processors are SGI, MIPS Computer Systems, Inc., Olivetti, Siemens-Nixdorf, Acer, Digital Equipment Corporation, NEC, and DeskStation. Operating systems ported to the architecture include SGI's IRIX, Microsoft's Windows NT (until v4.0),

So, ONCE there was A version of NT that had A release made specifically for A mips cpu...but this doesn't mean you can access -for instance- NT3 sources and port they from Rxxx to the modified R400032 (no TLB - no MMU - with FPU with VFPU)....forget it...i think it would be easier to adapt google's Android http://code.google.com/android/ (linux kernel with a beefy java virtual machine) to run on PSP, since it's designed to run on severly limited environments too.

EDIT: - MIPS is an intended target for Android to build, but to do so, we've to wait google to release the entire sourcecode (it's open, but they have no time 'cause they're still fixing SDK)

Android is based on Linux kernel 2.6 which, one assumes, requires an MMU which means PSP is out as a platform.
