I recently bought a cheap LuckyStar 5MVP3 rev 3 with a AMD K6-2 350.
Win98SE installs and runs when FSB is set to 95MHz or lower (tested 4*95 = 380MHz and 3.5*95 = 333Mhz).
If I set FSB to 100MHz and multi to 3.5, it shows up as 350MHz in BIOS but windows immediately shows a bluescreen on startup. Also when I try to run Win98SE setup from CD it gives me a SUWIN error. Same thing happens if I set the multi to something lower.
Switching back to 95MHz FSB and it's booting/installing fine again.
A capacitor near the AGP port shows some brown/red stuff on top, could this be the issue?
Other caps on the board look good.
I updated the BIOS to LEB7-03.4 already with no improvement (it came with version AU6-03).
Other hardware installed: 64MB PC100 SD RAM (tested with other working RAM PC66/100/133 of various size, same issue).
Voodoo 3 2000 AGP which works fine in my other vintage systems.
Quantum Fireball 13.6GB in UDMA33 mode using 80-pin wire (also tested with other working HDD and cable, tested in PIO mode too).
Non-branded AT power supply with unknown power output. Voltages are fine when tested with a multi, caps inside also look good too.
Via 4in1 v1435 drivers didn't help either.
Could this issue come from the capacitor with brown stuff near AGP port? Or maybe is the power supply broken or too weak? Any other ideas?
