SuperDOS--The REAL Propeller OS!

Here I present to you SuperDOS, which operates without ever removing itself from RAM! It functions like DOS, loading programs, and then executing them. Development is as easy as a normal propeller application. More to come in a couple days, including more info here and a ZIP file with EVERYTHING!

You now can select the pins you want in the installer!

To install:
1. Extract the archive.
2. Place the 'rsrc.dat' file onto the root of your SD card.
3. Compile the installer binary, changing pins etc. as needed, and download.
4. Follow the prompts to install SuperDOS!

    I'm planning to make an installer that can change the pins for you. Anyway, it will only last for today.

    I do not think I could do VGA, at least not without writing my own driver and keeping two completely different versions of SuperDOS. Also, programs might not be compatible between versions because one might take up more memory than the other. For example, the program 'chfont', which changes the AiGeneric fonts, will probably corrupt everything.

    So, we need an 8x8 VGA driver. This is long overdue anyway.

    All that really needs to be done is to replace the TV driver, leaving the rest of it alone. Well, after looking at it, color defs probably need to change too, but that's minor.

    Seems to me, the 8x8 code isn't all that hard to drop into a VGA framework.

    Anyone have suggestions for a target VGA driver to modify?

    I might have time this week to take a first pass at that, but will need somebody to test VGA. I've only got TV output test capability. (work with my Prop on the go, and use a capture card --how come nobody makes a VGA to laptop display thingy?)

    Let's see where I get to. Gotta pick through the various VGA drivers first. Need one that's fairly low resolution, so we can keep memory constraints sane.

    If you find one or two that seem to make sense, link them up here on this thread.

    tpw_man, would this impact your installer significantly, if the VGA driver were a drop in replacement?

    When can you post the driver Baggers? I can test it, and modify as needed. How much space does it eat up? It can't take much more than AiGeneric.

    also, is it on SD? if so, you could probably load in the driver as a binary, and then execute it pointing to a display buffer [noparse]:)[/noparse] that way it wouldn't take any ram whatsoever [noparse]:)[/noparse] other than the character map, and if you want with some small changes, I could change it so the font is in the cog also [noparse]:D[/noparse]

    As promised [noparse]:)[/noparse] one VGA 8x8 driver, modified from the 8x12 one posted on the forums a long while back.

    I've also added a plot routine, and print routine in the VGA_test.spin file.

    it shoud be very straight forward to incorporate it into SuperDos [noparse];)[/noparse]

    Baggers,

    and yes, potatohead it was hmmmmmmmm deeeeeeelish [noparse];)[/noparse] lol

    I've just made another function to plotprint·( ie it uses plot to draw the character, yes it's slow and doesn't erase what was under it but someone might have a use for it [noparse]:)[/noparse]

    More info about it here: http://forums.parallax.com/showthread.php?p=751612. Make sure you get the one in that post, and not tpw_rules' copy (his is a bit outdated and will destroy your filesystem if you work with files that use the same metadata).

    Basically all I did to get multiple file support was to move metadata / sd card related vars to DAT sections. I also added locking on I/O operations to prevent problems when multiple cogs are performing sd file access. There were a few other minor tweaks to get it to actually work, just run a diff to see what I did.
