Hello all.

I have managed to aquire a 3.8ghz Pentium 4 Cedar Trail proc. I would love to make a new Windows 98 system built around it. But I'm really struggling trying to find a motherboard that natively supports win98 and this particular late blooming processor.

Other wants are 4 Dimm slots and at least 2 IDE slots. Not fussed if it's Agp or PCIE.

I am also based in the UK so it's a bit harder to find decent secondhand motherboards of a certain age!

Any ideas?

ASUS P5PE-VM, AsRock 775i65G and ConRoe865PE are some of the boards which supports Windows 98 and Cedar Mill

And just wondering, is that 3.8 Ghz P4 is a Cedar Mill one?

Cedar Mill topper only at 3.6 ghz (Pentium 4 661) as i know

Pentium 4 5xx = Prescott with 1 MB L2
Pentium 4 6x0 and 6x2 = Prescott with 2 MB L2
Pentium 5 6x1 = Cedar Mill

About other mobos. Look LGA 775 Motherboards with AGP Slots

Is a list of AGP equiped LGA 775 mobos, but practically all of them supports Windows 98

Look at the CPU support of the model

Ahh my mistake! It's a Prescott with 2mb l2 cache. Still seem to struggle to find much that support this though. Is it worth going with this prwcott considering how hot it's going to run at 3.8ghz?

I've been running a Pentium 4 670 and a Pentium D 950 fine with the Intel stock cooler withot issues, but i used thermal paste instead of the preapplied paste in the cooler

So I have narrowed down the available motherboards to me (On ebay). This is what I have come up with.

AsRock 775VM8
Asus P5S800-VM
AsRock 775i65G (Blue version)

Out of these boards which would you think is the best? They all have full Win98 support and Cedar Mill.

Ideally I would rather have a 775VM800Pro-DDR2 or 775i65G black version, but they are pretty expensive or not available.

the last one, the AsRock 775i65G for the best perfomance (Intel chipset with dual channel RAM), the blue version can be ethier rev 1 or 2, when the black version is the rev 3 of the mobo, rev 1 only supports Pentium 4 and D, rev 2 supports 65 nm Core 2, when the rev 3 (black version) supports 45 nm CPUs like the Pentium E5800

if you don't need dual channel RAM, you can still look to the AsRock 775VM8 (VIA chipset based) or the ASUS P5S800-VM (SiS chipset based), i actually have the Asus P5S800-VM (rescued from a trash PC) and it works fine

Anything that uses Intel 925X(E) or older Intel chipset ?

Well, Cedar Mill officially needs a PCG 05A motherboard (VRM 10.0). Almost all early S775 motherboards are PCG 04A/04B.

Asus P4P800 SE/Pentium4 3.2E/2 Gb DDR400B,
Radeon HD3850 Agp (Sapphire), Catalyst 14.4 (XpProSp3).
Voodoo2 12 MB SLI, Win2k drivers 1.02.00 (XpProSp3).

Updated news: Managed to find a P4 661 top of the range Cedar Mill processor for free! So will definitely need one of those boards soon 😀

Since it was posted after my response.
Other than that, it is as you written.

Do you reckon its worth going for one of these?

MSI P4M900M2-L slot 775/533-1067 fsb/pcie-pci/sata150-ide-fdd/usb2/W98se-ME driver set

PCI-E, but has Win98 drivers (Sound and Video do not work though) Is it that hard getting PCI-E Graphics card working? I think its just editing an inf file mostly.

I can pick it up for about £30 with 2Gb of Ram. Or should I wait for some of the other mobos discussed?

Theoretically all PCIe Radeons (up to R400 aka X8xx series) and GeForces (up to NV4x aka 6xxx series) work ok in Win9x with last Win9x official drivers.
P4M900? IIRC this MB uses the DDR2 so this chipset is ok (P4M900 = single channel + DDR1 = very slow).
2 PCI slots + 1 PCIex1 slot is the main limiter.
100 Mb LAN is too slow.
I'm not sure there are VIA USB 2.0 drivers for Win9x.

Pretty sure the Asus P5S800-VM is a VIA Chipset that has USB 2.0 Drivers. Would those work even though the Chipset is different? Are USB 2 Drivers dependent on Chipset or are they independent? I don't mind using the universal USB driver if I have to.

Sorry I meant Asrock 775VM8. I have downloaded the USB 2 drivers for them and it is VIA. Should those work?
