Good luck Rahsennor.

Still a day+ to go, it will be interesting to see if you get a competitor.

I have an entry Smile

SHA1 hash of the archive file MIMOS10.ZIP, calculated by SlavaSoft's HashCalc is:
468f62eddbc30b2c7142642534dcc035d57dcfa5

unless I get time to do any more before 5.08am GMT (unlikely Sad

) in which case I'll post a new SHA1 hash.

The closing time has passed and no further work can be accepted. Is there some other post where you have placed BLOADER.INC? If not then it appears that your entry might not be valid Sad

Only one other entry! Shocked

readme lists bloader.inc as part of archive, but I don't see it anywhere. Did you just forget it?
Nice code, though. Much neater than mine... Embarassed

Hmmm, I don't know how that happened. I blame Windoze... Embarassed

BLOADER.INC is attached.

The only binary required, MIMOS.IMG, is in the archive however.

According to my reading of the rules my entry is still valid Idea

Thanks Rahsennor. I haven't looked at your entry yet. Will do so soon!

Okay, if the addition of BLOADER.INC generates the exact same .img file then I will happily accept your entry.

[edit] The image generated is exactly the same, so the entry is accepted

Rahsennor - Tea-7a.7z

neville - MIMOS10.ZIP+BLOADER.INC

Let's say two weeks to give everyone that is interested a chance to download and test and then we can see which way people want to vote.

Since there are not a great deal of entries then voting will be informal, people just need to say in this thread which of the two they want to vote for. Voting will end in three weeks from today.

Great, at least we have a competition Very Happy

Rahsennor, I've successfully assembled boot-lba28.asm, but I get "out of stack space" error when I try to assemble tea.asm. Any suggestions please?

Works for me:

I'm using my "development" PC which "only" has 256 MEGAbytes of RAM. I successfully assembled tea.asm on another machine with 1 GIGAbyte of RAM.
10228 bytes. Yea Very Happy

Then I was able to successfully assemble image.asm to generate image.bin comprising 4194305 bytes.

Now Bochs 2.2.6 PANIC's because "size of disk image must be multiple of 512 bytes". If I Continue it PANIC's again because "ata0/0 image size doesn't match specified geometry".

I'm not that familiar with Bochs but here's the bochsrc.txt file I'm using (most of which is commented out):

I'm determined to get tea running, or at least emulating Wink

Can anybody help?

Blame me for using a really old version of Bochs. Razz

I didn't bother to make the image the right size since my version ignores it. Shocked

Changing

Code:

      align   4096*1024
   db      0

Code:

  rb      512*63*16*8-1
       db      0

at the end of image.asm should pad it to the right size. Wink

EDIT: tea.asm compiles just fine on my old 64MB 700MHz laptop... Question

Yes, got it emulating now. Bochs 2.2.6 still PANIC's about the disk geometry but still boots with Continue.
I've now read Tut1 -> Tut6!

MiMOS successfully booted in Bochs 2.2.1. Vista Demo even had my laptop's fan on! Shocked

Did you learn anything? Laughing

I forgot to mention

Code:

timer .

should print a millisecond timer. I forgot lots of other things too, like how to write macros or spawn a new thread. That'll teach me for writing documentation at the last minute!

Yes, and Vista isn't very good at calculating time remaining Laughing

I guess I learn't a bit but I don't know Forth at all so that doesn't help Confused

Timer . prints hex strings of increasing value. I tried just "." a couple of times and I might have crashed it? Also Bochs seems to disable the mouse when running Tea, which can be fixed by pressing Ctrl-LB-RB on the console display?

Typing just "." will give a stack underflow. Embarassed

If you want to learn forth try Leo Brodie's Starting Forth. For Tea, don't forget the - probably incomplete - "Differences from Forth" section in Tea readme.

Tea doesn't use rats. Confused

Bochs setting?

MiMOS10.ZIP/MEMED.INC:

Code:

INIT:
                MOV     AX,0003H
                INT     10H

The INT 10H (00010000b) in MEMED.INC must be a random single-bit error caused by an act of God, or maybe a stray cosmic ray etc. Surprised

It is of course supposed to be INT 90H (10010000b) - the MiMOS video display service, called extensively by the MiMOS applications.

Please correct the single-bit error, and you will find the Memory Editor application (MEMED) runs perfectly. Cool

The preliminary winner of the REAL OS contest is Rahsennor.

Congrats, your prize will be issued later after the judges have completed their investigation and ensured that everything is proper.

Sad to see the contest end this way. Oh well, rules are rules, and breaking rules always has consequences. I imagine this was a moment of distraction for neville, where the brain goes into autopilot mode.

The competition rules enforcement officer hopes that the final remaining entry will also not have to be disqualified for some sort of technical reason. When the competition rules enforcement officer (that's me folks) has had time to go over the remaining valid entry to make a last and final check, then a formal and elaborate prize presentation ceremony will be given. Watch this space for updates.
