Hi, finally I have modified both DDOS12 and DDOS12dir so that they have the KILL bug corrected. I am attaching here a zip with the three 'new' versions: - DDOS13 corresponding to the old DDOS12 - DDOS13A related to old DDOS12A - DDOS13dir derivated from old DDOS12dir This last one will show as versi...

Hi Steve, hope to have the time tomorrow afternoon. Will give a peek at DDOS12dir as well, just to see if it is possible to do the same on it. As soon as have it/them tested, I will upload it/them here. Sorry for having changed the letter from A to B. It was just a way to distinguish them, so now we...

Hello, sorry I had not time to explain the last changes I made to correct the 1st DDOS12B file to the final uploaded version. According to the issue July, 1985 of Dragon User (correction of errata into patches of May-1985 issue), I found: - For Fault 6, the indirect table at the begining of the ROM ...

Hi, having read the Dragon Users of 1985-May and July, I have found two points in wich the old DDOS12B that I had uploaded in my previous message, differs from the suggested values to be chaged ... so I have updated it and do upload it again with the same name ... Please, if you had downloaded the D...

I have modified DDOS12A and renamed the result as DDOS12B Now it KILLs any file and restores all the sectors of every extent in the FAT So, presumably is a bit better than version 12A, but needs more tests to be done You can find it attached here regards pere PS. The modified version with the patch ...

Hi, I attach here the P G Scott's document about how to solve the DDOS1.0 problems and a document I have written with the differences that I have found comparing the two ROM files I will modify DDOS12A to restore the part of KILL destroyed by the b patch for Problem 2 (was not needed) At the same ti...

Hi Sixxie,

in fact the files I had were all of them 16132 bytes long, so no n x 256 bytes.
Once Stew has shortened them by the end to just 16128 (exactly n x 256) they work flawlessly

cheers

sorry,

I forgot to mention that DDOS12dir has the same problem that DDOS12 and DDOS12A with respect to the KILL command

cheers
pere

Ps. I am going to post a document with the diffrences between DDOS11C and DDOS12A and the PG Scott's patches doc in the other thread

Hi Stew, good point! You are right, if we want to use a 16k ROM we should deduct the range FF00 to FFFF that cannot be used (it's SAM domain) So $4000-$100 = $3F00 => 16128 exactly as you have said. No problem deleting from the end, because there is Nothing there ... Well, now we could use these bet...

Reading Philip Scott's patch document and referred to Problem2, he says that there are two ways to solve it: patch a) that impies solving Problem 1 too, and patch b) that implies reserving some RAM from $7FEF to store the patch there (code is PIC so could be allocated anywhere) In DDOS12A, Problem1 ...
