Hi Pino, Thanks for reporting success with running a K6-2+ on your PT-5VMX board with the 07/04/2000 BIOS! 😀 I will add this board and BIOS to my K6plus webpage at the next update. Regards, Jan

That's strange Jan...not for me; Firefox worked the other day but not today (same error), though IE11 does work today?? Curious, was Firefox just updated this morning? Assuming https if no http was forced is probably a good thing. Enhances internet security. :) IE11 is old and no longer updated, so …

Hi Douglar, Thanks for your interest in my Extbios tool. 😀 Nice that you found it in the internet archive. Note that my website is still live, however I had to move it to another domain. The patched K6plus BIOS repository gets a new home! Cheers, Jan

POST_CONF.JPG On the second picture there is something that bothers me. I marked it in red rectangle. Why this "APCI controller" has IRQ assigned without bus number? The ACPI controller is the hardware part of the ACPI interface between OS and motherboard. It isn't a PCI device so it doesn't get a …

Hi analog_programmer, I’m very pleased to hear you got the BX-6AP2 board running again! :) Great ! Yeah I do not think support for more PCI slots in bios (more ISA definately not) will be an issue, no different than having board with 5 slots and only using 2, the other 3 will be scanned and find …

Hi there, Jan. VLB video is garbled and memory test stops at 64MB and jumps to 128MB with "memory test fail" with the FordLian BIOS. With 1MB L2 cache installed, PCI video does not work. Without any cache stick PCI video works, 256MB RAM are detected and it reports 256K cache at the summary screen, …

Did you try the Award BIOS for the Ford Lian 9885AW board? https://theretroweb.com/motherboards/s/ford-lian-9885aw#downloads This 12/19/95-UMC-881E/886B-2A4X5CF9C-00 BIOS looks compatible with your M919 V3.x board and has support for the Am5x86.

Will 32211A BIOS (from XA100 Plus) work with XA100? Hi krysp, No, the Iwill XA100 board can’t use the XA100 Plus BIOS. It needs the version 32210A or 32210B BIOS. These BIOSes already have full K6-2CXT/K6-III support, so you only need a patched BIOS for a K6-2+/III+ CPU. The patched XA100 BIOS is …

Hi tauro, Thanks for your detailed feedback and good to know you selected the 1B7+ BIOS for this project! Also nice to hear the Unicore BIOS worked after all, albeit with lower performance.

Did you try without the Promise IDE card and run your drive(s) from the on board IDE port? Of course this will be slower because the 430FX southbridge doesn't know UDMA, but it will free up some resources. Not an MR BIOS, but I have a patched P55TP4XE(G) Award BIOS available on my Unofficial K6plus …

It’s a pity that the Unicore BIOS didn’t work. :( I’ve checked the 1B7 (02/04/99) BIOS and yes, it has a fix for the Win98 UDMA bug. Most 03/1999 and later Award BIOSes have this fix, but some as early as 11/1998 have it as well and the 1B7 is one of them. :) The CPU support in this 1B7 BIOS looks …

Right, jumpers J32 and J33 must connect to other signals or CPU pins than I thought. 😉 So the Normal (default) setting of these jumpers do work for the Am5x86. Great. Thanks for trying out my suggestions, Jan
