Installing Windows NT 4.0 does not recognize three major hard drive failures

  For some time, due to the need to work contact and install many Windows NT 4.0 systems (hereinafter referred to as NT4.0), accumulated some experience, will now install NT4.0 Some experience is available for your reference. Computer failure
  The first example is 586 compatible machine, MVP4 motherboard, K6-233CPU, 32M memory, 9750 graphics card, Maxtor 20G hard drive. The previously installed system was Win98, which is now converted to WinNT. Boot with Win98 boot disk, install NT4.0, restart the computer, the computer crashes. The problem of computer hardware can basically be ruled out. Because I have heard that NT power failure
4.0 does not support large hard disk, but the motherboard supports the large hard disk better, so the phenomenon is determined because NT 4.0 system can not recognize the large hard disk. And caused. The two files that NT 4.0 uses to identify the hard disk are atapi.sys and atdisk.sys. These two files can be found in the NT4.0 patch SP hard disk installation settings
6.0. Copy them to the "$win_nt$.∽bt" and "$win_nt$.∽ls" folders when NT4.0 is first started. After restarting, copy these two files to C:\\ This problem can be solved by winnt\\system32\\driver.
The second example is a 686 compatible machine with Gigabyte motherboard, PIII550 CPU, TNT2 graphics card, 128M memory and Quantum 20G hard drive. When NT 4.0 was installed, it crashed on the first boot. There is basically no problem with the computer hardware. The problem should also be caused by NT
4.0 not supporting large hard disks. Referring to the first case, copy atapi.sys and atdisk.sys into the "$win_nt$.∽bt" and "$win_nt$.∽ls" folders. After restarting the computer, it still crashes.
  Reason analysis: NT4.0 can not support large hard drives, but still can not work properly after installing the patch, it may be NT4.0 sensitive to the partition of the hard disk. Try to divide the large hard disk into only one 2G primary partition, the remaining space is temporarily not processed, reinstall NT4.0, everything is normal. But after NT4.0 was installed and the remaining space was re-partitioned with Fdisk, when NT4.0 was restarted, the computer crashed again.
  Reason analysis: NT4.0 crash may be related to the partition size of the hard disk, re-adjust the size of each partition of the hard disk, found on the partition of the hard disk, as long as the first 3 partitions are less than 8.4G, NT4.0 Everything is normal after startup. If it is greater than 8.4G, NT4.0 will crash when it starts up. At this point, the problem is solved.
The last example is a brand machine. The original configuration is ASUS motherboard, PII400 CPU, i740 graphics card, 64M memory and 4.3G hard disk. Because of an accident, the hard disk was damaged, replaced with a 10G hard disk, so reinstall NT
4.0 system. In the first boot after the installation, the machine crashes and tries to solve it by the above two methods, which are not effective. In desperation, first install Win98, then install NT 4.0, make a dual operating system, the problem is easily solved.
  The above problems in the installation of NT 4.0 are related to large hard drives, because NT 4.0 is released earlier, can not support large hard drives, so when installing NT 4.0 on large hard drives, it is more prone to problems I hope that these experiences can give a little hint to friends who install NT
4.0.
