Mbuye wagawanika ndi gawo la boot record / gawo lomwe liri ndi kufotokoza kwa magawo pa disk hard disk , monga mitundu yawo ndi kukula kwake. Tchati chogawanika chadongosolo chimaphatikizapo siginecha ya disk ndi ndondomeko yoyambitsa boot kuti apange mbiri ya boot.
Chifukwa cha kukula kwake (64 bytes) ya tebulo logawa mbali, magawo anayi (16 bytes) akhoza kufotokozedwa pa hard drive.
Komabe, zigawo zowonjezera zingathe kukhazikitsidwa pofotokozera gawo limodzi la magawo monga gawo lofutukuka ndikufotokozeranso magawo ena othandizira pa magawo ena owonjezera.
Zindikirani: Zida zogawikana za disk ndi njira yosavuta yogwiritsira ntchito magawo, kugawa zigawo monga "yogwira ntchito," ndi zina.
Maina Ena a Mndandanda Wopangira Mawokosi
Kawirikawiri pagawo lalikulu lamasamba limatchulidwa patebulo logawanika kapena mapu ogawikana, kapena ngakhale osankhidwa ngati MPT.
Gawo la Master Master Structure and Location
Mabukhu a boot amaphatikizapo 446 bytes code, wotsatiridwa ndi tebulo logawanika ndi 64 bytes, ndipo maulendo awiri otsalawo amasungidwa kuti asayinsidwe diski.
Pano pali ntchito yapadera ya maola 16 aliwonse a tebulo logawa gawo:
| Kukula (Zolemba) | Kufotokozera |
| 1 | Ichi chili ndi boot label |
| 1 | Kuyambira mutu |
| 1 | Gawo loyambira (zoyambira zisanu ndi chimodzi) ndi kuyamba kirinda (mabedi awiri apamwamba) |
| 1 | Chombochi chimakhala ndi mabedi asanu ndi atatu omwe ali pansi |
| 1 | Izi zili ndi mtundu wogawa |
| 1 | Kutsiriza mutu |
| 1 | Gawo lomaliza (mabotolo asanu ndi limodzi) ndi mapiritsi otsiriza (mabedi awiri apamwamba) |
| 1 | Chombochi chimagwiritsa ntchito mabomba asanu ndi atatu apansi |
| 4 | Mipingo yofunika ya kugawa |
| 4 | Chiwerengero cha magawo mu magawowa |
Chombo cha boot chimapindulitsa makamaka pamene mawonekedwe oposa omwe amayikidwa pa hard drive. Popeza kuti pali kusiyana koyambirira, boti ya boot imakulolani kusankha chomwe OS ikuyambira .
Komabe, tebulo la magawo nthawi zonse limatulutsa gawo limodzi lomwe limagwira ntchito monga "yogwira ntchito" yomwe imachotsedwa ngati palibe njira zina zosankhidwa.
Gawo la magawo a magawo a magawowa amatanthauza mawonekedwe a fayilo pa gawoli, pamene chidziwitso cha 06 kapena 0E chikutanthauza FAT , 0B kapena 0C amatanthauza FAT32, ndipo 07 imatanthauza NTFS kapena OS / 2 HPFS.
Ndi magawano omwe ali 512 bytes ku gawo lirilonse, muyenera kuchulukitsa chiwerengero cha makampani pa 512 kuti mupeze chiwerengero cha magawo onse a magawo. Nambala imeneyo ingathe kugawidwa ndi 1,024 kuti chiwerengerocho chikhale kilobytes, ndipo kachiwiri kwa megabytes, komanso kachiwiri kwa gigabytes, ngati kuli kofunikira.
Pambuyo patebulo loyamba la magawo, lomwe lakhala la 1BE la MBR, magawo ena a magawo awiri, gawo lachitatu, lachinayi ndi lachinai, ali pa 1CE, 1DE, ndi 1EE:
| Kutsegula | Kutalika (Zolemba) | Kufotokozera | |
| Hex | Kutsika | ||
| 1BE - 1CD | 446-461 | 16 | Gawo Loyamba 1 |
| 1CE-1DD | 462-477 | 16 | Gawo Loyamba 2 |
| 1DE-1ED | 478-493 | 16 | Gawo Loyamba 3 |
| 1EE-1FD | 494-509 | 16 | Gawo Loyamba 4 |
Mukhoza kuwerenga ndondomeko ya tebulo logawa mbali ndi zida monga wxHexEditor ndi Active @ Disk Editor.
