I read the articel „Socket 7: Fit For Years To Come!“ here at tomshardware.com. It was really good!
Then I ordered a K6-2+ 500 MHZ - CPU. I have got a Tyan Trinity 100 AT Mainboard with 128MB SD-RAM 100 MHz. Bevor the K6-2+ I had a Cyrix MII PR300 which was working fine but slow in games.
I installed the K6-2+ CPU. I set the Voltage to 2,0V, the FSB to 100 MHz and the factor to 5. All other jumpers are set as before (with Cyrix CPU). If I turn on the Computer, nothing is happening. The screen stays black. If I turn in my old CPU, set the Voltage and factor back, everthing is working.
In the BIOS-Settings I have turned off Cyrix-Support. I have tried BIOS-Version 1.16c (newest) and 1.16. But it doesn´t work. I have also tried factor 4.
Can anybody tell me what I can do?
I only want to send the CPU back to my dealer if I am sure that it is not OK.
Today I got the same configuration as yours to work. After much gnashing of teeth as to why the pre-revision 5 S1590 (Trinity 100AT) board would not recognize the K6-2+/500 (same as in the July, 2000 article in Tom's Hardware,) the answer came, albeit in a roundabout way. While perusing this forum this morning, I noticed a link to the AMDZone (www.AMDZone.com.) Once there, I backed out of that particular post (same problem as ours, but with an Asus P5T [I think]) and found the forum on K6's. In the K6 forum was a reply to a post from an individual who advised the original party to "...get Jan's patched 1.16c BIOS..." or words to that effect. The link was even highlighted, so I downloaded it, replaced the 1.16c BIOS downloaded from Tyan, and voila! The system recognized the processor for the first time, and, I might add, identified it correctly as a K6-2 Plus.
I should mention that as of now the settings are pure vanilla: The 500 MHz processor is being driven 100 x 5. The Tyan 2.0 volt jumper setting did not work for me, but the 2.1 volt setting works just fine. Now to see how stable this thing is. I restore vinly LPs to CD, and the process involves massive FFT processing. I really can't afford
to have a system that may run a bit faster, but in an erratic manner.
Ive just done the same upgrade on a Tyan trinity 1598s and low and behold blank screen and no boot, just like yourself.
Had to take it back in the end
sorry I cant help, hope youve got it running now, thanks to Jan
