Beta bios for KT7/KT7-RAID/KT7A/KT7A-RAID/KT7E



!!! For Evaluation Only !!!



0. Based on beta BIOS KT7_3R.B01 and KT7_3R.B02

1. Update BIOS code.

2. Enhance ISA PnP compatibility.

3. Enhance SCSI adapters compatibility.

4. Add 1400(133) Athlon support for KT7A/KT7A-RAID.

5. Add new option "1200 above" for high speed Athlons with 100FSB.

   KT7/KT7-RAID/KT7A/KT7A-RAID/KT7E only support 1.4G(100) Athlon

   with L1 bridges disconnected. Check L1 before you buy a CPU please!

6. For Creative SBLive 5.1 sound card users, you may try these

   options while experience sound quality issue.

     .PCI master read caching, default setting=Disabled

     .PCI master time-out, Default setting=1

   Setting above options to Disabled/3 will lead to the same

   result with VIA Latency patch V0.14 and may help SB Live 5.1

   sound issue. If the system experiences low performance after

   these settings, enable the "PCI master read caching" please.

7. Change HPT BIOS to 1.11.0402 for KT7-RAID/KT7A-RAID. This BIOS

   version is also for non RAID boards and HPT BIOS will be

   automatically disabled while RAID controller chip not detected.

8. Enhance the high speed 133FSB Athlon stability for KT7A/KT7A-RAID.

9. Side effect: CPU temperature becomes higher, about 50 degree C

   while gets into Windows 2000 and ME.

   Solution: Overwrite offset 52 bit 7 to "1". This can be done by

   special utilities WPCREDIT and WPCRSET.

A. Fix the HOST+PCI memory clock malfunction problem.

B. BIOS compile date: 07/05/2001



   !!! Attention for upgrading KT7-RAID / KT7A-RAID BIOS to 3R !!! 



When you upgrade bios from ZT to 3R, we highly recommend you backup

your system and data to an independent storage device first. New HPT

1.11.0402 bios may corrupt original RAID configuration created on

old bios occasionally. That means you may need to rebuild RAID

configuration. If it happens, all the data on RAID-0 will be gone! 



For RAID-1 user, please press "CTRL+H" to enter hpt370 setup screen 

and do "Duplicate Mirror Disk " to recover RAID system.
