Added legacy USB keyboard and mouse support. 2. Removed a feature that disabled the DIMM clocks for unused DIMM sockets because of problems with the ICS9248 clock chip. 3. Fixed a problem where it would take up to 1 minute to boot from the hard drive if both an ATAPI Zip drive and an HP 8100 CD-RW drive are attached to the system and the Zip drive is selected as removable media. 4. Fixed a problem where the system would go into suspend while the user was in setup. 1.04: 1. Added AUTO option for Legacy USB feature. Setup default set to AUTO. 2. Added support for SST39SF020 flash part. 3. Added new Video BIOS for Rage128 (rlt5bx1c.112 v611) 4. Microcode update for Katmai Slot 1 C0. 1.05: 1. Fixed a problem when using a serial mouse on COM2 with legacy USB set to Enabled or Auto. 2. Fixed a problem where Katmai C0 microcode updates were not applied to the Pentium III CPU. 1.06: 1. Updated Katmai C0 stepping CPU microcode (mu167305) 2. Fixed a problem with corrupted UDMA strings in setup when the hard drives were selected as user type. 1.07: 1. Fixed a problem where IRQ5, which is required by the Riptide legacy audio function, might be used by another add-in PCI card by reserving IRQ5 in setup. 1.08: 1. Added support for the Mosel-Vitelic V29C51002T flash part. 1.09: 1. Added a feature that will always enable the Diamond Monster Audio PCI card no matter what the setting of the "Installed O/S" setup option. This allows the DOS mode driver to find and configure the card. 2. Added a feature to always prevent IRQ5 from being assigned to a PCI device if either the Diamond Monster Sound or Riptide audio cards are installed. (Note that this does not modify the value of the corresponding setup option, which can still be used to reserve IRQ5). 3. Fixed a problem where HDD and CD-ROM drives might be listed under the removable format option in setup. 4. Fixed a problem with the Diamond Viper V770 AGP card where the BIOS would sometimes not allocate the appropriate memory resources to the card, causing a POST failure of 1 long and 2 short beeps (indicating an OPROM checksum failure), followed by no video display. 5. Fixed a problem where if an HDD is set for USER type, the Ultra DMA Mode option in setup would allow the user to select type 3 or 4 even though the system does not support these modes. 6. Fixed a problem where if the user would reload setup defaults while in setup, the option for Pentium III Serial Number support would disappear. 7. Changed the "Installed O/S" string from "Win98/WinNT5.0" to "Win98/Win2000".Download Driver Pack
