Pentium with 90Mhz, 32M RAM and 512K L2-cache. Works extremely well (a kernel recompile takes 10 minutes :-).
The board includes:
Pros: Currently, I'm using it with an Adaptec 1542CF and a 1G Seagate drive, No problems. Graphics is ATI Graphics Pro Turbo (PCI). Very fast. The serial ports can keep up with a TeleBit T3000 modem (38400) without overruns. Caching above 16M does occur. There are 3 banks of SIMM slots (2 SIMM's per bank), with each bank capable of 64M each (2 32M 72-pin SIMM's). Each bank must be filled completely to be used (I'm only using bank 0 with 2 16Mx72-pin SIMM's). The CPU socket is a ZIF type socket. The BIOS is Phoenix, FLASH type.
Drawbacks: RAM is expandable to 192M, but the L2 cache is maxed at 512K. While the graphics are very fast, there is currently no XF86 server for the Mach64 (well, actually there is, but it doesn't use any of the accelerator features; it's just an SVGA server). I don't know if the onboard IDE hard drive controller works; I'm prejudiced against a standard that won't allow my peripherals to operate across platforms, so I didn't buy an IDE disk; instead, I got a Seagate 31200N and a NEC 3Xi.

The motherboard I eventually bought (in the UK) is one supporting 486 SX/DX/DX2/DX4 chips. It is called SA486P AIO-II. Features include:
I bought it from a company (UK) called ICS (note I have no connections whatsoever with the company, just a happy customer). I use a 486/DX2-66 CPU.
Before I had a VLB 486 m/board with a buslogic BT-445S controller that I was borrowing. I have 2 scsi devices: 1 barracuda 2.1GB ST12550N disk and a Wangtek 5525ES tape drive. I was expecting a lot of adventures by switching to the new motherboard, esp after hearing all these non-success stories on the net. To my surprise everything worked flawlessly on the 1st boot! (1.1.50). And it has been doing so for about a month now. I did not even have to repartition the disk: apparently the disk geometry bios translation of the 2 controllers is the same. Linux has had no problems at all. SCSI is visibly much faster as well (sorry, I have no actual performance measurements). The only problems (related to Drew's linux ncr scsi driver - thanks for the good work Drew!) are: lilo cannot boot from the scsi disk unless you manually edit /etc/disktab (a one-off simple procedure). (2) disconnect/reconnect is disabled; ditto with synchronous negotiation. The former just causes scsi ops to "hold" during certain lengthy tape operations (eg rewind). The latter just looses some extra spped. These will not be a problem in the near future. I hear Drew is working to fix them.
I had a small problem with MS Windoze! On win startup I get this warning:
The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded. There is unrecognizable disk software installed on this computer. The address that MS-DOS uses to communicate with the hard disk has been changed. Some software, such as disk-caching software, changes this address.If you aren't running such software, you should run a virus-detection program to make sure there is no virus on your computer.
To continue starting Windows without using the 32-bit disk driver, press any key.
This is not really a problem. All works fine after this. And if I remove the WDCTRL driver from the SYSTEM.INI I get no warning. But I am wondering whether I am loosing in performance (it does not look like it). I can state that this problem did *not* appear with the buslogic VLB 445S scsi controller.
All else is fine. I tried the serial ports with some dos/windows s/w and worked ok. The IDE/floppy work ok as well. I have not tried the parallel yet. The motherboard is quite fast and so far I am very pleased with the upgrade. I have not yet tried a PCI graphics board. I will later on. I am using an old ISA S3 which is fine at the moment).

Gateway2000's P5-66 system with Intel's PCI motherboard, with 5 ISA slots and 3 PCI slots. The only PCI card I am using is the # 9 GXe level 12 PCI card (2 MB VRAM and 1 MB DRAM). This card was bought from Dell. Under Linux I am using the graphics in the 80x25 mode only (I am waiting for some XFree86 refinements before using it in 1280x1024 resolution), but under DOS/Windows I have used the card in 1280x1024x256 mode without problems. Etherlink 3C509 Ethernet card, Mitsumi bus-interface card, Adaptec 1542C SCSI interface card and additional serial/parallel ports card (which makes the total of serial ports 3).
I have total of 32 MB RAM (recognized and used by both Linux and DOS). There is also a bus mouse (Microsoft in the PS2 mode).
No problems so far.
Gateway 2000 P5-60 with an Intel Mercury motherboard, AMI-Flash-BIOS, (1.00.03.AF1, (c)'92) 16M RAM, on-board IDE controller and an ATI AX0 (Mach32 Ultra XLR) PCI display adapter. He had absolutely no problems with the hardware so far but has not tried anything fancy, such as accelerated IDE drivers or SCSI support.
SPACE-board, 8MB RAM, S3 805 1MB DRAM PCI 260MB Seagate IDE-hard disk because of lack of NCR53c810-Driver, 0.99pl15d, does seem to work well.
17 machines running a 60Mhz-i586 on Intel-Premier-PCI-Board
Motherboard - Intel Premiere Plato-babyAT 90mhz with Buslogic bt946c w/4.86 mcode w/4.22 autoSCSI firmware, (note, mine came with 4.80 mcode and 4.17 autoSCSI firmware. (interrupt pins A,B,C conform to respective PCI slots!) ATI Xpression (Mach64) - using driver from sunsite, (running AcerView 56L monitor).
The motherboard has 4 IDE drives, Linux (Slackware 2.0) sees the first two and everything on the Buslogic as it emulates an adaptec 1542. Uh, yes, Dos sees them all. Buslogic is VERY accomodating in regards to shipping upgraded chips (you will have to know how to change PLCC (plastic leaded chip carrier) chips, 3 of them. Though, don't let that scare you :-) it's not that tough. Get a low end PLCC removal tool, and your in business. You also might want to "flash upgrade your system bios from Intel's IPAN BBS, a trivial process. Whats even more interesting is I also have a Sound Blaster SCSI-2 running a scsi CDROM drive off it's adaptech 1522 onboard controller. So thats 4 IDE drives (2 under Linux) and 2 SCSI-2 controllers.
I hope this helps others who are struggling with PCI technology use Linux! Jerry (jeromem@xnet.com)

It is giving no problems. He uses SLIP for networking and an Orchid-Soundwave-32 for niceties, awaiting the NCR-Driver. The only problem he has is that the IDE-Drive could be much faster on the PCI-IDE. It is one of the new Western Digital fast drives and in DOS/WfW it absolutely screams - on Linux it is just as slow as a good IDE-Drive.
Archie and his friend have rather similar configurations:
The onboard-SCSI is disabled. First there were problems with the IDE-drive: ``on the board there's a jumper which selects whether IRQ14 comes from the ISA bus or the PCI bus. The manual has an example where they show connecting it to PCI INT-A. Well, we did that just like the example... but then later our IDE drive would not work (the IDE controller is on board). Had to take it back. The guys at NCA were puzzled, then traced it back to this jumper. I guess the IDE controller uses IRQ14 or something? That's not documented anywhere in the manual. Other than that, seems to be kicking ass nicely now. Running X, modeming, etc. (for the Supra you have to explicitly tell the kernel that the COM port has a 16550A using setserial (in Slackware /etc/rc.d/rc.serial))''.
uses the following:
It runs perfectly and I am content with the speed, the ATI-GUP-PCI (Mach32) does not give as good benchmarks as expected, though. If I had the money I'd get me an Intel Premiere-II (Plato chipset) with P90 and number-9 GXE64Pro... I keep on dreaming :-)
He uses a Gateway 2000 with no problems, except the soundcard (which one?). He is trading it in for a genuine soundblaster in hopes that will help.
originaly buyed a 486 DX2/66 from ESCOM (which board?) with onboard IDE and without (!) onboard NCR-SCSI-chip. ISA-adaptec 1542cf scsi-controller instead spea v7 mercury lite (s3, PCI, 1MB), ISA-Soundblaster-16, mitsumi-cdrom (the slower one). Everything except the archive-streamer works with no problems. The spea-v7 works perfectly since XFree86-2.1
He abandoned the Intel-board in favour of an ASUS-SP3-g and has some problems with PCI-to-Memory burstmode which is crashing only on Linux, "looking like a deadlock in the swapper". If you have any information on this, please eMail the maintainer of the PCI-HOWTO.
After turning off the PCI-to-Memory posting feature it just works perfect.
Rather than sending him mail please read his http-homepage at "http://wsiserv.informatik.uni-tuebingen.de/~jw" where he keeps information about his PCI-system, too.
ASUS-PCI board with AMD486dx40 (but actually running at 33Mhz?!) His ISA-ET3000 Optima 1024A ISA works nice.
