Will not help but ran into similar situation with a P4 board and it's latest BIOS included a microcode for a specific CPU I had but it still would not work proper.
Curious why you think microcode 686 is newer than 68A.
Also is possible that the newer BIOS actually dropped some CPU support. There are some topics here on Intel boards where they did remove some cpu support for a few models but added support for other CPU's.....
Just not enough room in the BIOS for all the microcodes....

Yeah the Ace should be high in this instance. 😀 Well actually not all that high A counts for 10 decimal in hex.

Sorry I meant that the date of revision of the microcode 0686 is newer 5/2000 than the one for 068A 2/2000. I’ve ordered the C step processor just to see. It was only $15 shipped.

Way cheaper than the 286 -> cx486slc board I just bought for waaaaay too much money. I hope it will fit in my compaq portable II or I wasted a lot of cash! At least the Pentium III works… just without the microcode.

I did try bios 32 (the one that introduced the 068A processors) and it didn’t work either.

There's nothing in the BIOS history regarding microcode removals - v16A added 0686, v32A added 068A, v33A added 0683 & v35A added 0686 - and updates being cumulative, v35A should still support the lot. How were you running the BIOS updates - from (DOS) diskette, from the CD ISO or from the OS. I see a similar issues to yours online for a model 6578 which was fixed by running the diskette rather than the OS version (they were upgrading from a 733/256/133 SL3XY to a 1GHz/256/133 SL52R)

I was doing it from within windows. I’ll give it a go from diskette tonight and report back.

BIOS flash from floppy fixed it!

Thanks x1000!

Hi, where did you get new bios for it ?
I've got Netvista 6059 PCG but don't know where to find newer bios for it.
Thank you

You need to go here: http://ps-2.kev009.com/pccbbs/netvista/
Find PIJT35A.exe and create the floppy, follow the pijt35a.txt exactly !! That is the last BIOS update for NetVista(R) model 6059-xxx,
Note once you flash to BIOS past T31A it becomes very hard to go back......

Thank you !!!

What about pijt37a or 36a which is for 6059 also...
Found it in
http://ps-2.kev009.com/pccbbs/netvista_bios/
Not sure if this is for this model or not...

Did you read the 36 and 37 .TXT ? Those do not add any extra CPU support but do support 6059. And from what aspiringnobody said above he either used the floppy version of 32 or 35 with success (hard to tell which ;p )
It might work but trust PC Hoarders opinion on trying 35a. He has good search and computer knowledge and since that was the latest to include cpu updates. If aspiringnobody was online he could tell which it was..
Ohh and if you are running like 30a now you cannot easily go back and risk bricking the board if 36 or 37 do not work. If me would try 34 or 35 (the last with improved CPU support) but only IF I was planning to upgrade the CPU.
Maybe someone else has tried 36 or 37..

Yes, I've read the txt and it says it is for 6059. The previous updates are exactly the same for all the versions. 36 and 37 has only couple of fixes, no cpu code updates. Will check what bios I've got and might try that 37.....

I ended up putting a Tualatin in it after what was posted above. The default bios will update the microcode if done from the floppy. If you look at the floppy it creates you will see all the supported microcode updates included with that bios -- and you can delete ones you don't need and add in support as needed. The microcode and the bios are treated as two separate operations.

I'm headed to bed now but I think I've got a flash floppy image on my usb stick with the latest bios + the tualatin microcode that should work for coppermine and newer. I'll get it posted tomorrow.

This img file has the microcode added for 06B1 Tualatins -- as well as the 068A needed for coppermine. If you have a 06B4 Tualatin this won't work for you -- you'll need to download the bios from a later IBM netvista, create the floppy or otherwise extract the microcode file, and delete one of the ones you don't need from the root directory of this floppy to make room for the 06B4 microcode. Then, when flashing the bios the microcode will be included automatically.

EDIT: This mobo needs the little adapter that is sold on ebay to solder to the bottom of a tualatin to make it work on an older board. With the patch I've uploaded there won't be any errors on boot using this method. If you're using coppermine then none of this is necessary -- you just need to flash the bios with the image included below, after putting the coppermine in the PC.
