Hi folks, I recently bought a used HP Pavilion to use for testing. The machine works fine with no problems. I wanted to increase the CPU to give it a bit more umf. It is currently a 466mhz celeron PGA so I bought an FC PGA adapter (powerleap neo s370) and a 733mhz FC PGA coppermine CPU. When I install this combination I hear some whirring from the box then nothing. The power LED for the adapter is on. The model can be found here: http://www.hp.com/hpinfo/abouthp/histnfacts/museum/personalsystems/0035/ The model number on my machine is p1352a (its a japanese box). I checked the compatibility chart for HP pavilion and NEO s370 and Im pretty sure it should be ok. http://64.4.34.250/cgi-bin/linkrd?_lang=JA&lah=d9d9e768ce9da1cce1dbad2a46ea67c8&lat=1075882512&hm___action=https%3a%2f%2fwww%2equickbase%2ecom%2fdb%2f6v74ue7a%3fact%3dq%26amp%3bquery%3d%7b%271008%27%2eCT%2e%27PL%2d370%252FT%2520OR%2520PL%2dNeo%252FT%27%7d%26amp%3bclist%3d1008%2e1017%2e1023%2e1015%2e1021%2e1002%2e1003%2e1016%2e1006%2e1012%2e1014%26amp%3bslist%3d1002%2e1003%26amp%3bopts%3dsortorder%2dAA%2egroupby%2dFF Any ideas on how I should proceed? some extra details: Program: Unicore BIOS Wizard Version 3.23 Program: eSupport.com BIOS Detect v1.2 July 21, 2003 BIOS Date: 04/20/00 BIOS Type: American Megatrends BIOS ID: 63-0126-009999-00101111-071595-WHITNEY-1AAHD026 OEM Sign-On: T8383 Rev. 1.1.00 Chipset: Intel Whitney 82810 rev 3 Superio: SMC LPC47M10x rev 1 found at port 2Eh OS: Microsoft Windows 98 Version: 4.10.1998 CPU Type: Intel Celeron(tm CPU Speed: 466 Mhz CPU Max: 800 Mhz BIOS ROM In Socket: Yes BIOS ROM Size: 512K Memory Installed: 128 MB Memory Maximum: 1024 MB Memory Slot 01: 64 MB Memory Slot 02: 64 MB

sorry this is the compatibility link. i tried to edit the original message but it didnt work!!?????? https://www.quickbase.com/db/6v74ue7a?act=q&query={'1008'.CT.'PL-370%2FT%20OR%20PL-Neo%2FT'}&clist=1008.1017.1023.1015.1021.1002.1003.1016.1006.1012.1014&slist=1002.1003&opts=sortorder-AA.groupby-FF.

Possibly a jumper on the motherboard to change FSB frequencies? I should think the older Celeron ran at an FSB of 100MHz, while the newer chip more than likely has an FSB of 133MHz. If the correct FSB has not been selected, then the symptoms you are describing will take place.

thanks FSB was 66mhz , new and old processors are both 66mhz and adapter was set for that. however, the solution was that I was testing without the cpu fan plugged in. The old CPU booted without it but the new one didn't (weird). I didn't actually need the adapter (waste of money) so i guess my board supported PPGA and FC PGA all along.
