Hey does anyone know why it's bad to mix X87 and SSE instructions?
Slak
can anyone help me with some problems in asm?
can't reverse a proggie ... pls some expert help (for informational purposes)
ike-
Slak, still here?
Slak
yes
what is it ike-?
i was out for lunch :)
ike-
pai sa`ti fie de bine
:)
Slak
mersic
ike-
ce cracuiesti?
Slak
un soft pt tamplarie pvc
termopane
ike-
:)\
         

Slak
are o protectie foarte paranoica
:)
ike-
tell me
Slak
cand executi programu afiseaza un spalsh screen
in screenu ala iti arata codul prg si trebuie sa bagi un cod care ti-l dau ei
care sa se potriveasca cu codul proggiului
ike-
hmmm... gen hardware dependent
Slak
probabil
ma gandesc ca acel cod al prg testeaza seria de hdd sau ceva
ike-
ai mai cracuit pana acuma
Slak
dar codul care il bagi tu e relationat de codu ala
mici
prg mici
winace, mirc ...
ike-
:)
Slak
asta e f ciudat
ike-
pai stii sa fol ida?
Slak
nope
fol w32dasm
hiew
si softice
faza e ca nu pot sa ii dau un bpx in softice calumea
ike-
w32dasm e vechi si prost... te enerveaza si nu e bun de mai nimic
Slak
si se incarca in 100+ ani :)
hai sa iti zic o chestie
ike-
deci: cauta pe net ida si ollydbg
zii
Slak
cand introduci codu face testare realtime
in timp ce tastezi
daca tastezi codul corect iti da enable la butonu de OK
daca nu ... e enabled doar ala de iesire
acum caut ida
ike-
heh, ai incercat cu windows enabler sa`i dai click pe el? ce se intampla?
Slak
heh
:)
i-am dat enable cu resource hacker
dar
nu are nici un script atasat
scriptul porneste doar daca e codul corect :)
am gasit si olly
olly e huge
ike-
?? ce vorbesti?
e mititel
Slak
atunci am eu link de toata mana probabil
:)
mda
mere netu prost
:)
ike-
stai sa vad daca il am p`aici..(`s la servici)
2 mega...
         

Slak
eu am reusit sa gasesc jumpul care verifica codul introdus
cand il inversez insa imi intra in demo mode :(
ike-
hmm... poate se verifica... ceva gen checksum
sau jumpul ala face altceva
Slak
hmm
daca vrei pot sa iti trimit si tie kitu programului si te joci si tu cu el ...
ca il am in mail
ike-
e mare?
Slak
7megi
ike-
mah... ti`ash zice sa mi`l dai dar is cam ocupat... maine am examen si trb sa invatz...
Slak
hmm
dar nu e graba
iti trimit in mail si tu te uiti cand poti
ike-
uite ce facem, mi`l dai si cand am timp, ma uit pe el
Slak
super
da mailu pe privat
Deathmaster
lol canalul asta ar trebui sa se numeasca #asm.ro

anyone knows how I can format a large disk? there doesn't seem to be any function among the int13 extensions (at least in ralf browns list)
Slak
hehe
Deathmaster
lee: there's no function to format a hdd... you must write "format" it yourself
Slak
or u can use a bootable windows CD
Deathmaster
i mean build the fat and everything
Chiu_Lee
there are the format track (and set bad sector) functions for floppy and small disks using CHS addressing
Deathmaster
slak: he wants to do it with int13ext so i'm sure he wants to it in some program he's writting
Chiu_Lee
something like that. no filesystem is involved
Slak
hmmm
Chiu_Lee
just to check and flag bad sectors
the verify function (44h) does not flag bad sectors
Deathmaster
lee: bad sectors are flaged inside the file system
for example in fat12/16/32 for every bad cluster you have a special value in the cluster array
Chiu_Lee
so the int13 functions actually are overwritten by the os?
edcba
format functions do bad sectors
Chiu_Lee
if so, what does the function for formatting do on bot for example when no os is loaded?
Deathmaster
lee: int13 functions are not overwritten by the os, nothing formats the hdd when no os is loaded
Chiu_Lee
hm...
Deathmaster
for example when you install msdos or win32 the setup formats the hdd if no fat/ntfs file system is present but the setup counts as the os
even though it's completly automatic
Chiu_Lee
then why doesn't that get specified in the interrupt list? seems a little odd.
Deathmaster
what are you talking about? what do you think should appear in the int list?
msdos/windows setup internal formatting functions?
Chiu_Lee
soemthing that will say: don't use this function unless the os is loaded
I am not talking about dos/windows
as I sad there is no filesystem involved in my app. and no os either
I am writing a disk utility app, btw
so basically the app IS the "os" (just like that setup you mentioned)
Deathmaster
lee: you still don't understand... there's no formatting and no "bad cluster" unless you have a file system
Chiu_Lee
I see...
Deathmaster
and btw int13 ext functions only give you support for accessing large disks (if you don't wanna comunicate with the hdd directly), you should read more carefuly... any formatting action is file-system specific and must be done by the os "manualy"
Chiu_Lee
I would read more carefully, but there is nothing about that in the int list ;)
eh, guess I'll rething my app then
rethink*
edcba
you shouldn't format hard disk anyway
Deathmaster
why shouldn't he?
edcba
because he would do mistakes :)
Chiu_Lee
:)
edcba
and now hd care themselves about sector errors
Deathmaster
i'm sure he tests it in an emulator first
i know i would
Chiu_Lee
a vm actually

Chiu_Lee
thanks. I got specs-edd11.pdf from somewhere yesterday, just didn't get to read through. (besides being old)
ghimpe--
can any one help me divide 19 to 100 and store the 0.19 value in a variable, i'm trying to do this since 3 days and i'm out of luck
edcba
now do the same but multiply all values by 65536
