N1KTxxA is the flash image level. (BIOS) NOTE: All changes carry forward. That is, if a change is added in 60, it is also in 61, 62 etc. CHANGES for N1KT/N1JT60A Updated S3 Bios for Rapid Resume Problem with Brooktree DAC CHANGES for N1KT/N1JT61A Fixes for Firemans Fund , trap errors during warmboot. Clear all memory on warm boot. CHANGES FOR N1KT/N1JT62A 3/7/95 PNP adapters coflict with IDE resources. Fix when a plug and play card is installed, the IDE hardfile sometimes does not configure in setup. ISA CONFIG STRUCTURE REVISION WRONG Fix for plug and play bios causes problem in the ISA Adapter Configuration structure. Clear Shadow RAM Region From C000-DFFF PCI adapters when using this address space cause an NMI to occur when EMM386 is loaded. Password entry forced on warm boot w/Prompt Off With the Password Prompt set to "Off", the system behaves correctly on a cold boot. The system boots with the keyboard locked and the keyboard is unlocked when the user enters the password. Once the password is entered on the cold boot, it should not have to be entered again on a warm boot, but the keyboard still comes up locked and waiting for a password on warm boot. It does operate correctly when the Password Prompt is set "On". The system does not prompt for the password on the warm boot. Serial/Parallel Port Fixes POST does not reset FIFO mode of planar serial ports on reboot. POST resets traditional registers only and leaves planar serial ports in enhanced mode. Japan - Harddisk parameters at 0:300h-0:33Fh destroyed From Japan - The interrupt vector area 320h-36Fh is occasionally destroyed, apparently by the C2 Security code. As per the Japanese code fix for this, the routine setvecs will be called after the C2 security code has been called. This will restore the vector area that is occasionally being destroyed. Password messages displayed in English only This is a fix for messages displayed when a password is deleted or change is always displayed in US English, regardless of which country the Flash is for. QEMM386 Stealth Mode hangs system Fix for hardfile errors when running QEMM386 in Stealth mode CD_ROM message corrupt Ptr fixed setup messages that were getting corrupted. --------------------------------------------------------------------------- CHANGES FOR N1KT/N1JT63A 3/18/95 Windows exits to C:> prompt When running "eXceed 4" from Hummingbird, the system will occasionally abort Windows. Sometimes, the user will be left at the C:> prompt. Sometimes, the system will halt with an error #6 message from EMM386. Other software programs that use the nmi interrupt vector could fail similiarly Fix Brazil MRI Code added to support Brazil, and make it fit on the flash diskette LOCKUP AFTER AUDIO SETUP Fix when audio setup is DMA 1/Disabled choice. System locked up in POST 1802 WITH PCI VIDEO ADAPTER Fixed 1802 message from appearing when certain PCI video card request IO space Clear Software Interrupt 67h during POST. Fix for specific applications that use int 67 vector. They expect it zeroed out. Update Century byte if rollover while in setup Fix for century byte rolling into the year 2000. Force boot sector checksum to be updated if not initialized The F1 keystroke is intermittantly lost F1 entry to setup is intermitently lost under some warmboot conditions. --------------------------------------------------------------------------- Changes for N1KT/N1JT64A 5/15/95 ** Never Released ** 1355 Check_DMA_Active is setting a carry not AX. Caused an intermittent hang on Rapid Resume 1392 Suspend/Resume timing with Modem. Caused an intermittent hang on Rapid Resume with modem 1645 Change Boot Sector Virus checking to disabled (as a new default) 1655 Fix audio hangs on warm boot with soundblaster. This fixes a hang condition if a WAV file is being played when the warm boot is started. 1656 Skyline (IBM PCI Token Ring) adapter hangs on warm boot 1759 Fixed Audio with Win95. Plug and Play information was reported incorrectly and no audio was available. 1760 Configure additional non-conforming CD-ROM devices Allows certain CD-ROM drives that do not conform to the ATA CD_ROM specification to be recognized. 1762 Prevent hang on request for storage size 0 from option ROM. 1763 IRQ7 resource conflict between Audio and LPT1. This was for win95 fix 1764 AZERTY keyboard "m" key not usable for password fix 1765 Add NEC Monitor support to DDC1. Delay added to allow detection of monitors that do not support the application notes of the spec. --------------------------------------------------------------------------- Changes for N1KT/N1JT65A 5/19/95 1777 German will not build - Space problem in Flash fixed --------------------------------------------------------------------------- Changes for N1KT/N1JT66A ** Never Released ** 1826 Add chip support enhancements. --------------------------------------------------------------------------- Changes for N1KT/N1JT67A 1851 Set ISA legacy default for IRQ 10 to not available 1844 Add latest S3 BIOS 1834 Disable the video early in POST on warm boot so the machine does not appear to be hung. 1880 Mach5-MC Update for Languages (100, 120, 133, and 150) mhz processors. Support added to distinguish these speeds. 1810 Second IDE CD-ROM on the same cable not recognized 1866 Hang in Adaptec PCI SCSI full screen setup. --------------------------------------------------------------------------- Changes for N1KT/N1JT68A 36095 Skyline (IBM PCI Token Ring) adapter fixes --------------------------------------------------------------------------- Changes for N1KT/N1JT69A 7/11/95 36106 S3 Video Changes --------------------------------------------------------------------------- Changes for N1KT/N1JT70A 7/20/95 36124 PCI multifunct cards get different IRQs now on request. 36264 System hangs with audio default to off when boot fail count > 3. If system failed to boot 3 times, the audio would default to disabled. This hung preload. Now default is enabled. --------------------------------------------------------------------------- Changes for N1KT/N1JT71A 7/21/95 36100 Mouse hang after Rapid Resume in Windows 95 If user moves mouse during apm shutdown, mouse function may be lost at resume. 36120 PCI adapters not enabling memory if there is no option rom on the card 36229 PCI POST does not handle ROM images > 64kb PCI BIOS does not handle ROM images greater than 64k correctly. The bit map of real memory area is not updated correctly if ROM image is larger than 64k. 36230 Clear screen before displaying logo. 36257 Century will now roll to year 2000 during POST and using CMOSclk.SYS DOS driver 36315 S3 Video BIOS update --------------------------------------------------------------------------- Changes for N1KT/N1JT72A 8/14/95 35680 Setup: Some security items are selectable when they cannot be used. 36340 Fix AZERTY keyboard pointer so we do not lose it (for French keyboard only). 36460 Move audio from IRQ 7 to IRQ 10. Preload is also changing at this time. Move parallel port to IRQ 7. This removes conflict in IRQ allocations that caused problems with PCI cards installed. 36520 Clear cache on warmboot for hang condition with WAV files on Sound Blaster. 36568 Add support for greater that 64 meg memory when using Windows NT or Windows/95. 36658 Correct spelling errors in German language. --------------------------------------------------------------------------- Changes for N1KT/N1JT73A 8/15/95 ** Never Released ** no changes made build system failure --------------------------------------------------------------------------- Changes for N1KT/N1JT74A 8/16/95 ** Never Released ** 36673 DDC1 monitors not always setting up correctly. Not always selecting the fastest refresh rates possible for the monitor. --------------------------------------------------------------------------- Changes for N1KT/N1JT75A 8/21/95 ** Never Released ** --------------------------------------------------------------------------- Changes for N1KT/N1JT76A 8/22/95 36463 Some 4X CDROMs do not show up in system summary 36617 Disable IRQ 9 if certain PCI cards are installed. This change fixes adapters that require IRQ 2 or 9. IRQ 9 will now only be disabled if certain PCI token ring cards are installed. The adapters that are known to be fixed with this change are 3278, 3270, ISA token ring and any other that require IRQ 2. --------------------------------------------------------------------------- Changes for N1KT/N1JT77A 9/05/95 35218 Keyboard password is lost during reboot 36976 Suspend/Resume fails with certain CDROM drives 36992 Cache size may be incorrectly reported 36997 IDE and SCSI Hardfile attachment hangs the system. 37003 Save/Restore Video Mode When Clearing Screen in POST 37017 OEM no logo build is no longer building properly --------------------------------------------------------------------------- Changes for N1KT/N1JT78A 9/05/95 37163 Fix for Shutdown of Win95 with PnP cards. --------------------------------------------------------------------------- Changes for N1KT/N1JT79A 11/01/95 37366 Power switch becomes non-functional (very intermittant) The symptom is that the machine does not power down when the switch is depressed. Removing the power plug would reset the condition. 37791 Drives on secondary controller may falsely report not busy and therefore not be recognized during POST. 37792 Int 15 Function E820 returns incorrect values if EBDA was moved by The operating system. No known problems have been encountered. 38528 Change stack pointer during int. 19 to prevent stack overflows. Some PCI SCSI adapters were overlaying the stack and causing various errors including hangs during POST. 38564 Add changes.new file to flash diskette. This will allow the users to see what changes have been made in order to determine if they need to upgrade their systems. 39036 Update video BIOS to correct cursor problem when using Windows at 1024X768X8 at 72Hz. --------------------------------------------------------------------------- Changes for N1KT/N1JT80A 11/09/95 39324 Fix intermittant 201 (memory parity) errors. (No customer reported problems - only seen in manufacturing test.) --------------------------------------------------------------------------- Changes for N1KT/N1JT81A 01/30/96 39353 Some PCI video cards conflict with other PCI devices 39559 162/184 config error. Very intermittantly, false configuration errors occur on power up. 39852 PCI PCMCIA Adapter not recognized --------------------------------------------------------------------------- Changes for N1KT/N1JT82A 04/17/96 43691 Cache line size may be set incorrectly on some PCI adapters 41816 Space Saver Keyboard does not work on CTR ALT DEL 39798 Some installations get EMM386 Exception Error #12 --------------------------------------------------------------------------- Changes for N1KT/N1JT83A 06/27/96 47849 Defect 39353 fix in level 81 was deleted somehow. 45876 OPTION ROM Signature not found on one Token Ring Ntwk Card causing it to not be detected. 48380 Change the PCI allocation of IRQ 9(2) for video. If the ISA LEGACY SETUP reserves IRQ 9, the reservation will be honored. It previously ignored the reservation and gave the IRQ to PCI video always. This change allows old ISA cards that can only use IRQ 2 to now be able to get that IRQ assigned. The default for video is still IRQ 9 if it is not marked as reserved. 49383 1762 error after adding 6X or 8X CDROM Drives. The problem is an error in the chipset on the drive. However, we will change the detection code to get around the chip problem. This only fails on drives with one vendors chipset. Changes for N1KT/N1JT84A 07/19/96 1762 error after adding 6X or 8X CDROM Drives. This corrects a problem that caused the drives to hang when they were attached as a slave, or would also hang a hard disk if it was attached as a slave to one of these drives. This failure only occurred with certain combination of CDROM drives and certain hardfiles. ======================== Changes for N1KT/N1JT87A 05/09/97 66960 Bypass of password with boot (rpl) prom. With certain network cards and the power on password set, the password is not prompted for when it should be. Changes for N1KT/N1JT88A LPT3 fails after APM events when using WIN/95. 110 errors in POST with memory installed in all slots and Intel P54CTB upgrade processor installed. Test programs checking "Year 2000" under DOS could fail even though the clock updated correctly.
