OGOZI KORI SISTEMAI MS DOS

Tavre ki qayd karda shud, sistemai operatsionii MS DOS ba uayr az digar amaliyotho, hamchunin baroi idora kardani kompyuter niz istifoda burda meshavad. In programma dar disket yo diski vinchester nigoh doshta meshavad. Diske, ki dar on sistemai operatsioni sabt karda shudaast, diski sistemavi nomida meshavad.

Pesh az on ki kompyuter ba yagon namudi faoliyat ogoz namoyad, boyad hatman az diski sistemavi sistemai MS DOS ba khotirai favrii kompyuter (RAM) dokhil karda shavad.

Ravandi ba khotirai kompyuter dokhilkunii sistemai MS DOS-ro ogozi kori kompyuter megeyand.

Tartibi ijroi in amaliyot chunin ast:

•  Agar sistema az disket dokhil karda shavad, boyad on ba diskdoni yakum (A:) guzoshta shavad va dar bloki sistemavii kompyuter tugmai Poweq pakhsh karda shavad.
•  Agar sistema az vinchester dokhil karda shavad, on goh pakhshi tugmai Poweq kifoya ast.

Pas az pakhshi tugmai Poweq kompyuter ba dokhilkunii sistemai MS DOS shuru menamoyad. Pesh az hama, sistemai BIOS ba kor omoda budani qismhoi kompyuterro mesanjad.

Bad sistemai BIOS ba diski sistemavi murojiat menamoyad va az sektori yakumi on programmai ogozkunandai kori DOS-ro mekobad. Pas az yoftan onro ba khotirai kompyuter dokhil menamoyad va idorakunii kompyuterro ba on mesuporad.

Programmai ogozkunandai kori DOS az diski sistemavi faylhoi Io.sys va Msdos.sys–ro yofta onhoro ba khotirai kompyuter dokhil menamoyad. Bad az katalogi asosii diski sistemavi fayli Config.sys khonda meshavad va komandahoi dar on nishondodashuda ijro karda meshavand.

Dar holati umuman mavjud nabudani fayli Config.sys yo purra ijro shudani komandahoi on, az katalogi asosii diski sistemavi programmai Command.com ba khotirai kom-

pyuter dokhil karda meshavad va idorakunii kompyuter ba on suporida meshavad. Bad, programmai Command.com az katalogi asosi fayli Autoexec.iat–ro mekobad va dar mavridi yoftani on, komandahoi dar in fayl joydoshtaro ijro menamoyad. Pas az ijro namudan yo nanamudani fayli Autoexec.

bat dar satri komandavii MS DOS informatsiyae barovarda meshavad, ki on davatnomai sistema nom dorad.

Paydoshavii davatnomai MS DOS dar ekran az on dalolat medihad, ki sistema baroi qabuli komandahoi istifodabarandai kompyuter omoda ast.

Agar MS DOS az vinchester dokhil karda shavad, on goh davatnomai sistema metavonad namudi zerinro doshta boshad:

S:\>

Dar holati az disket dokhil namudani sistema, davatnomai on namudi digarro megirad:

A:\>

Istifodabarandagoni kompyuter muvofiqi tabu khohishi khud, metavonand davatnomai sistemaro tagyir dihand.

Satri ekran, ki dar on davatnomai sistema joygir shu-

daast, satri komandavi yo komandaho nom dorad. Komandahoi ba vositai klaviatura dokhilshavanda mahz dar hamin satr nishon doda meshavand va pas az pakhsh kardani tugmai

dokhilkuni ijro karda meshavand.

 EZOH:

1. Dar holati dar katalogi asosii disk mavjud nabudani fayli Autoexec.iat programmai Command.com az istifodabarandagon dokhilkunii tarikhi ruz va vaqti joriro talab menamoyad. Tarikhi ruz va vaqtro az klaviatura dokhil menamoyand. Agar zarurati dokhilkunii tarikhi ruz va vaqt naboshad, on goh tugmai Enter –ro pakhsh menamoyand.
2. Dar ibtidoi ravandi dokhilkunii sistema, ba ekran informatsiyai «Staqting MS DOS» barovarda meshavad. Agar dar mavridi paydo gardidani in informatsiya, darhol tugmai F5 pakhsh karda shavad, on goh faylhoi Autoexec.bat va Config.sys ijro namegardand va prog–rammai Command.com dokhilkunii tarikhi ruz va vaqtro talab menamoyad. Pas az dokhilkunii in malumotho dar ekran davatnomai sistema paydo megardad.
3. Agar dar holati paydoshaviii informatsiyai «Staqting MS-DOS» tugmai F8 pakhsh karda shavad, on goh imkoniyat paydo megardad, ki faylhoi Autoexec.bat va Config.sys qadam ba qadam ijro shavand. Aniqtarash, pesh az ijro namudani amaliyoti navbati pursida meshavad, ki on ijro karda shavad yo ne. Hangomi pakhsh kardani tugmai Y (yes) komanda ijro karda meshavad va dar vaqti pakhsh namudani tugmai N (No) boshad, komanda ijro karda nameshavad.

Hotirrason menamoem, ki dar sistemai MS DOS ba har yak qismi kompyuter nomi shartii muayyane doda shudaast:

 A: – diskdoni yakum baroi disketho.

 B:– diskdoni duyum baroi disketho. Hangomi dar kompyuter

vujud nadoshtani diskdoni duyum, B: – nomi duyumi diskdoni yakum hisob karda meshavad.

 C: – diskdoni diski vinchester.

 D: – diskdon baroi kompakt–diskho (CD-ROM).

 Con – nomi klaviatura, dar vaqti dokhilkunii informatsiya va nomi ekran, hangomi khorijkunii informatsiya (Son – kon-sol).

 Prn – nomi printer.

 

 Savolho:

1. Diski sistemavi gufta kadom diskro meguyand?
2. MS DOS chi tavr kori khudro ogoz menamoyad?
3. Tartibi ijroi qismhoi MS DOS chi guna ast?
4. Dar ekran paydoshavii davatnomai MS DOS daleli chist?
5. Satri komandavii MS DOS chi vazifa dorad?

 Suporish:

1. Matni mavzuro bodiqqat khoned va onro naql kuned.
2. Dar daftar mukhtasar tartibi ijri qismhoi MS DOS–ro navised.
