Hello and welcome 😀

For Tualatin build look for VIA Apollo Pro 133T chipset (aka VIA 694T). https://www.vogonswiki.com/index.php/List_of_ … 70_motherboards
I'm not sure about BIOS support for Pentium 3-S (512kB cache version). However if it is Award BIOS you can add microcodes using cbrom. http://www.rom.by/

If you want to buy retro stuff I recommend amibay.

Thanks you 😀
Im attaching a picture of my Tualatin cpu. Is the 512kb cashe a problem ? are there other versions with more/less L2 cashe ram?

512kB cache is not a problem at all, it provides increase of performance in opposite to regular 256kB versions.
However those 512kB cache processors were intended to use in servers (P3-S as "S"erver), so desktop boards does not have to provide microcodes for them. Anyway, many of desktop boards supports those out-of-the-box.

BTW. I have exact the same processor as yours.

Allright thanks 😀
Great if Win98 games supports it, i love playing Quake 2 😀
Whitch motherboard do you use with your cpu then?

Currently I don't have any board which supports Tualatin. Previously (with P3-S 1266/512) I used FIC FS35T. In the past I also had MSI MS-6337 v5.
Those two are Intel 815EP so unfortunately no ISA slot. I don't know any i815 board with ISA.

Still reading/getting info, no 815 does not have ISA slot, VIA has, but the Intel chipset is better.
But my build needs my AWE32 soundcard so i can emulate MIDI mode 😀

You can use PCI YMF7x4 instead. For DOS games inside Windows 98 (when using VxD drivers) you can use its hardware MIDI synthesizer as MPU401. For Doom, Duke3D, etc. It also has good plain DOS support (SbPro, Adlib - real OPL3).

Leave AWE32 in Pentium 2 build.

ISA gives you more flexibility in a DOS built - *usually* PCI sound cards do the job well enough, but they have limits. A PCI YMF7x4 requires a PC/PCI (SBLINK) connector to work properly under DOS. Motherboard with that are rarer than motherboards with ISA. If you want a flexible solution that doesn't need anything more than a PCI slot, try cards based on the Ensoniq/Creative ES137x-series, or - better IMHO - C-Media's CMI8378 chipset.

As for how to get ISA with Tualatin support... the boards certainly exist, but are rare and therefore also tend to be pricey. A cheaper option might be to go for a Slot1 motherboard with Coppermine support and ISA slots, and use a Slocket to plug the socketed CPU into a slot board. Dedicated Tualatin slockets are rare and expensive, but common, cheap Coppermine converters such as the MSI MS-6905 can be fairly easily modded to make it work anyway.

YMF-PCI cards can operate similar to Creative PCI cards with EMM386 dependent emulation via the DSDMA utility. Creative cards are common, inexpensive, and work okay for the most part. They can be susceptible to a few types of chipset specific bugs that can impact sound quality and they don't support any MIDI emulation in pure DOS mode. Several other vendors like Yamaha, ESS, and Aureal provide solutions with more versatility in terms of operating modes and chipset compatibility with full MPU-401 support in pure DOS mode. There are a few other vendors with solutions that haven't been comprehensively evaluated, so I can't comment on them.

Avoid CMI8378 cards for pure DOS, though, as compatibility is spotty at best.

Hello everybody, im new here, i will have some noob questions, bear with me 😀
My retro interrest exploded in early 2018, started collecting Amiga, then Commodore 64, Then made a youtube channal to share my passion.
Few days ago, i watched LGR and Philscomputerlab videoes, listend to MIDI music in games, and now IM HOOKED ON DOS 😀

Hey.... And welcome... 😀
You finally made it in here, after I recommended Vogons in your comment section of one of the Video's.

Welcome, haven't seen your PII video yet (at work) but will definitely check it out.
I'd agree with zyga64

The PII wil make a good fast dos gaming PC, if anything some games will run too fast, leave your isa sound card in there.
A PIII offers no benefit over a PII for dos, AGP isn't needed until WIn9x gaming either, Your CPU makes a great start for a Windows 98 gaming PC which has much better PCI sound cards.
and if its 2 player C&C your wanting you can always either fire up the PII into windows or use the not perfect but good enough dos emulation on the P3 with one of the PCI cards mentioned above

Guys, thanks for the great advice, I really appreciate it.
Currently im working on a pentium 1 machine, link for more info:
