Nothing! Very dissapointed here! Cry

Seems as chip does not wake up. It is getting hot but not too much.

For example in epox 8k5a2+ error postcode 25.

It always gets same error with test socket and now with chip soldered onto card.

Would be very important to know more details about the card. If it stoped to work because RN112. If card was fully working once left 3Dfx. If we had at least the scheme internal Power Supply... Sad

Regards,
Oscar.

Or does the three resistors that replace it properly do the job?

If they are the same, then the problem is somewhere else.

No since those resistor pack are custom for 3Dfx and no other card uses such resistor pack. According to Hank with the 4 smd resistor soldered at the card should do the work as well.

Must clean the others chips and later check if there is a number on them.

Seems my Rampy card comes with an old bios.
Gary's Rampage bios is dated 07/12/2000 as well. So, my bios is only 2 days old than yours.

Regards,
Oscar.

Just noticed this post Oscar- e-mail me your BIOS and I'll reinstall my hex editor program which will let me compare the two. This will give us vital information about how and where to make BIOS changes.

I was lucky, Hank answer me.

According to him,

Check Y1, the big silver component, with a scope you should see 14.3MHz clock. This is important or the chip core will not run.

Check voltages across the capacitors marked bellow. Record them and compare them to the working Rampage.

3 things are necessary to get the chip going.

The Power, the clock and the reset. Look at these first.

According to Oscar,

Checked voltage:

Michel's rampy / Oscar's rampy

C252 - 1.280 - 1.265
C276 - 2.360 - 2.373
C210 - 1.915 - 1.922

EDIT:

C232 - 3.275 - 3.290

Voltage seems correct.

About crystal Y1 - He doesn't have any tool here for MHz mesure. His multimeter dont have such option and he doesn't own any osciloscope though. Any tip? a cheap osciloscope or multimeter with such option.

Regards,
Trevor.
