Hmm, it would seem congratulations are in order Rahsennor, although you must be disappointed to "win" this way Laughing

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.

I have excluded all INT's below 32 for two reasons. 1) to avoid confusion with the standard BIOS function calls. and 2) to meet the original Intel spec of the reserved interrupt space being 0-31. If you want to use hardware interrupts in your OS, then, to meet the rules, you will have to move the PIC base to at least 32 (higher if you want, but not lower).

rahsennor, of course you have every right to insist on a strict enforcement of the rules, if thats what you mean by your post above. Confused
But in this case it means there is no competition at all, and you "win" by default. Smile
I think this competition had a lot of merit and was well conceived by revolution. It must also be very disappointing for him that it should end with such a small wimper. Shocked It deserved better Cool
Just for the record, my decision to add the AX=3 function to MiMOS's INT 90H video services function was made at the last minute. It is just a "clear (text) screen" service because "set video mode" is not (yet) implemented. This function is used everywhere successfully in MiMOS apps, but I must have inadvertently typed INT 10H in the Memory Editor source code. Of course it still tested OK so I didn't realise the mistake. My fault, I didn't check more thoroughly. Embarassed However I believe it is only a "technical" breach of the rules. MiMOS implements all required functions, independent of the BIOS as required. Razz

Nah, I'm all nitpicked out. Laughing fasm must have a really tiny userbase if only two people can enter such a simple contest. I agree, great idea, real shame nobody else entered.

As for the int 10h, I vote we call it an "application bug". Razz Seriously, it doesn't even do anything. Since I used int 09h that makes us all square. Cool

Okay, since you two are the only entrants I will ask you what you want to do.

1) Do you want to restart the voting with the current entries and just ignore the "int's lower than 32" restriction? This way your entries are not wasted.

2) Do you want to me to give you both something like 1 day extra to fix the entries and then start voting again? Note: That substantial modification would probably not be allowed, only enough of a change to get the entry compliant would be accepted.

3) Do you want to do something else (like maybe abandon the contest)?

Do not abandon the contest.
The first year of any activity is always less spectacular than subsequent events.
Next year's contest will be much more active, I predict.
Further, you are laying the groundwork here, for a useful technique to improve the FASM forum.
Please do not abandon it.

The solution to the present imbroglio is clear:
Provide an extra one month, until Halloween, say, and encourage others to apply, emphasizing the importance of limiting all entries to those efforts which eliminate use of bios interrupts.

Engineers are assigned to build a bridge. The completion deadline date is given. The date arrives, but the bridge remains unfinished. What, now they should all go home, because of the date? No, they need to keep working at it, a bit more diligently, keeping in mind the requirement to avoid ALL metal, i.e. use of ONLY natural, not man made materials.

My preference would be for option 1) Smile Option 2) would be OK too because I would probably only have to amend that INT 10H to INT 90H. I don't think it would be fair to re-open the current competition to new entries, but I would encourage another similar comp in the future and hope that more people would enter 2nd time around.

For option 2 I'd have to rewrite my bootsector - but if you really want to keep the rules I do have PIC-remapping code. If I find time. Neutral

Don't forget to consider tom tobias's suggestion also. Let's call it number 4 option.

4) Reopen the contest to more entries, closing date October-31.

What nonsense is this? Are we still in kindergarten where "everyone is a winner"? Razz

i ask for a new date like in my theory about | motivation vs time |

start the contest in october with bios allowed (because bios is on all machines)

stop it in april

rest for spring and summer

start again with no bios and a common executable format.

...

As the two guys broke the rules (BIOS ints one..), I think it is fair enough
to continue and as if nothing happened, and put the entries for vote.

I wish I could participate, but I was coding my os in real mode,
so alots of bios ints where there. Wink

Also I highly recommended to make another contest in the comming
monthes.

Good luck guys.
