సరైన సమాధానం BIOS.

 

  • ఆపరేటింగ్ సిస్టమ్ యొక్క బూట్స్ట్రాప్ లోడర్ ప్రోగ్రామ్ యొక్క మొదటి సూచన BIOS(బేసిక్ ఇన్ఫుట్/అవుట్ఫుట్  సిస్టమ్) లో నిల్వ చేయబడుతుంది.
  • బూట్స్ట్రాప్ లోడర్ అనేది EPROM, ROM లేదా యంత్రం యొక్క ఇతర అస్థిర మెమరీలో ఉండే ప్రోగ్రామ్.
  • పరికరం ఆన్ చేయబడినప్పుడు ఇది ప్రాసెసర్ ద్వారా స్వయంచాలకంగా అమలు అవుతుంది. కంప్యూటర్ యొక్క ఆపరేటింగ్ సిస్టమ్‌ను ఇన్‌స్టాల్ చేయడాన్ని కొనసాగించడానికి, బూట్స్ట్రాప్ లోడర్ హార్డ్ డ్రైవ్‌ల బూట్ బాగాన్ని చదువుతుంది.
  • యంత్రం స్విచ్ ఆన్ లేదా తిరిగి ప్రారంభించినప్పుడు, బూట్స్ట్రాప్ లోడర్ మొదట పవర్-ఆన్ స్వీయ-పరీక్షను నిర్వహిస్తుంది, దీనిని POST అని కూడా పిలుస్తారు.
  • POST విజయవంతమైతే మరియు సమస్యలు కనిపించకపోతే బూట్స్ట్రాప్ లోడర్ యంత్రం ఆపరేటింగ్ సిస్టమ్‌ను మెమరీలోకి లోడ్ చేస్తుంది.
  • ఆపరేటింగ్ సిస్టమ్‌ను పొందుపరచడం, లోడ్ చేయడం మరియు ఆపరేట్ చేయడం యంత్రానికి సాధ్యమవుతుంది.
  • EFI (ఎక్స్‌టెన్సిబుల్ ఫర్మ్‌వేర్ ఇంటర్ఫేస్) ఉన్న కంప్యూటర్లలో, బూట్స్ట్రాప్ లోడర్ భర్తీ చేయబడుతుంది మరియు ఇది ఇప్పుడు EFI BIOS లో భాగం.
