While treating nt3.51 after installing 80Gb I've meat trouble with accessing partitions above 2Gb (fat32) under nt3.51. And I've got BSOD - INACCESSIBLE_BOOT_DEVICE. The problem was found inside scsidisk.sys (it is called disk.sys under nt4). It doesn't detect ExtendedX, Fat32, Fat32x,Fat16x partitions. I've rebuilt scsidisk.sys. And now everything works fine. Along with this there are still some useful thing in my collection. They help running NT 3.51 on new hardware and with some new applications.

\BOOT - ntldr/ntdetect.com nt's boot files needed for large hdd support (from Windows2000SP4) \DLL - comctl32.dll (from IE 6 SP 1) - common controls, cfgmgr32.dll & setupapi.dll needed for NT device/program managment (see SDK/DDK). \FAT32 - fat32 support for nt 3.51 (replace original fastfat.sys) -- only Fat32 & Fat32x partitions (no ExtendedX support!!!) \FONT - ISO 9241 Part 3 Compliant 8x16 Fonts for Dos FullScreen (+Cyrillic) - very readable at screen!!! (replace original ega.cpi) also suitable for nt4/xp \RENEW - recompiled serial.sys for more stable and fast 56k+ modem connections \RENEW - recompiled scsidisk.sys, atdisk.sys & atapi.sys to support large drives under 3.51 (without LBA48 support yet) \VIAIDE - VIA EIDE driver from VIA Service Pack! works with nt 3.51! \VBEMP - VESA 2.0/3.0 driver for nt 3.51 (see http://www.geocities.com/bearwindows/vbemp.htm)

* \DLL - Replace commctl32.dll (from IE 6 SP 1). After replacement of this file I could run 1C Enterprise 7.5 (and 7.7 too) 😀 under nt 3.51.
* \BOOT - ntldr/ntdetect.com nt's boot files needed for large hdd support (from Windows2000 SP4)
* \FONT - dos fullscreen font ISO-compliant - very readable at screen!!! Replace original ega.cpi. Is also suitable for nt4/xp
* \FAT32 - fat32 support for nt 3.51. Replace original fastfat.sys.
* \RENEW - recompiled with 3.51 ddk scsidisk.sys & atapi.sys (from nt4) to support large drives under 3.51 (sorry without LBA48 support yet) + sources. New serial.sys which works more stable with 56k+ modems is also located here.
