The following devices are components of \plain\f2\fs20\b PIIX4/PIIX4E\plain\f2\fs20 : \par \pard\plain\f2\fs20 \par \pard\li1440\plain\f2\fs20\b Intel\'ae 82371AB/EB PCI to ISA Bridge \par Intel\'ae 82371AB/EB PCI Bus Master IDE Controller \par Intel\'ae 82371AB/EB PCI to USB Universal Host Controller \par Intel\'ae 82371AB/EB Power Management Controller \par \par \pard\li720\plain\f2\fs20 In \plain\f2\fs20\b Microsoft\'ae Windows\'99 95\plain\f2\fs20 , special device information \plain\f2\fs20\b (*.INF)\plain\f2\fs20 are used to specify and define the characteristics of various controller and device classes of the operating system. These *.INF files can be found in the \\WINDOWS\\INF directory. \par \pard\plain\f2\fs20 \par \pard\li720\plain\f2\fs20 However, the PCI Device Ids for the functions embedded in the \plain\f2\fs20\b PIIX4/PIIX4E \plain\f2\fs20 component is not listed in the current versions of the Windows\'99 95 specified below. \par \pard\plain\f2\fs20 \par \pard\li1440\plain\f2\fs20\b Version 950\tab \tab Windows\'99 95 (Retail Release) \par \par Version 950A\tab \tab Windows\'99 95 OEM Service Release 1 (OSR1) \par \par Version 950B\tab \tab Windows\'99 95 OEM Service Release 2.0 (OSR2) or \par \pard\li3600\plain\f2\fs20\b Windows\'99 95 OEM Service Release 2.0 plus USB \par Supplement (OSR2.1) \par \pard\plain\f2\fs20 \par \pard\li720\plain\f2\fs20 For this reason, after installation of Windows\'99 95 in \plain\f2\fs20\b Intel\'ae 430TX, 440LX/EX, 440BX \plain\f2\fs20 systems, many devices are not recognized and therefore will have \plain\f2\fs20\b either ! or ? in Device Manager. \par \pard\plain\f2\fs20 \par \pard\li720\plain\f2\fs20 To solve this problem, changes to the \plain\f2\fs20\b MACHINE.INF\plain\f2\fs20 , \plain\f2\fs20\b MSHDC.INF\plain\f2\fs20 , \plain\f2\fs20\b NODRIVER.INF\plain\f2\fs20 and \plain\f2\fs20\b USB.INF\plain\f2\fs20 (for version 950B) must be made. \par \pard\plain\f2\fs24 \par \par \plain\f2\fs24\b II.\tab SOLUTION \par \par \pard\li720\plain\f2\fs20 Modifying the\plain\f2\fs20\b *.INF\plain\f2\fs20 files require an enormous amount of time and patience. For this reason, this utility will modify the \plain\f2\fs20\b *.INF \plain\f2\fs20 files for you. Your original *.INF files will be backed up with the *.000 extension. \par \par Take note, however, that this only applies to the versions of Windows\'99 95 described above. \par \pard\plain\f2\fs24\b \par \par III.\tab EXPLANATION ON USB \par \par \pard\li720\plain\f2\fs20 For \plain\f2\fs20\b Windows\'99 95 OSR2 plus USB Supplement (OSR 2.1) release, \plain\f2\fs20 USB is already \par supported. No additional USB drivers are needed. \par \par For \plain\f2\fs20\b Windows\'99 95 OSR2\plain\f2\fs20 , \plain\f2\fs20\b USBSUPP.EXE\plain\f2\fs20 must be installed first, before running this utility. USBSUPP.EXE can be acquired from Microsoft. \par \par For \plain\f2\fs20\b Windows\'99 95 950 and 950A\plain\f2\fs20 , USB is not supported and therefore no drivers are \par necessary. \par \pard\plain\f2\fs20 \par \plain\f2\fs24 \par \plain\f2\fs24\b IV.\tab CONCLUSION \par \par \pard\li720\plain\f2\fs20 Hope that this utility will simplify Windows\'99 95 installation in\plain\f2\fs20\b Intel\'ae 430TX, 440LX/EX and 440BX \plain\f2\fs20 systems. \par \par }
