Dear Gurus, These are the details of my bios in the B684 (Procomp/Pine) mobo: BIOS Manufacturer : Award Modular BIOS v4.51PG BIOS ID : 04/12/1999-i440LX-ALi513-2A69JPNBC-00 BIOS Date : 04/12/99 BIOS OEM Signon : B684 BIOS Ver:1.3 BIOS ROM Size : 128K Chipset : Intel 440EX/LX rev 3 Super I/O Chip : A...

Thank you, Rainbow, for clarifying that.

Do not known how to answer your question. However, the document 29040609.pdf mentioned that the letters just in front of the "150" (speed value" can take the value T for top bootblock or B for bottom bootblock.

The 29C010D also.

Dear Gurus, Cannot figure this one out. Have successfully hot flashed bios with UNIFLASH. Bios seemed to work ok but when the saved file of the flashed bios is compared to the source the checksum is different? The flashing included the overwriting of the bootblock of course! This happened with 2 dif...

Thank you for the info Mr. Denniss. Use awdflash sometimes but playing mainly with UNIFLASH now to gain as much knowledge first before learning other flash s/ware.

Also acquired a strange chip, marking as follows:

M506/7 9-1
CN007
549C5C73AQI

Cannot be identified by UNIFLASH even at 12volt.
Anyone seem this kind of marking before?

The HT 22025 is detected by UNIFLASH as MACRONIX MX 28F1000T/12V and the HT36580 as 28F010/12V.

1st report/ Tried to flash the ASD AE29F1008-15 using UNIFLASH 1.29. I did a A>uniflash -e xxxxxxxx.rom without using the -force command it to see what would be the result. Was surprised that UNIFLASH proceeded to detect the chip straight away as W29x010 and started to write! So Rainbow was right! F...

Thanks. Will try them out.
