The Epiphan cards have a programmable EDID function in the drivers. You can tell your source whatever kind of monitor you have connected.

Sounds like some weird chipset limitation or the BIOS isn't properly updating the e820 memory tables. I know the SiS EISA chipset and AMIBIOS has no problems with RAM above 64MB.
Re: VGA Capture Thread
Posted on 2021-11-16, 17:27
XSplit should work with any DirectShow capture device, which the Datapath and Epiphan cards are. Technically you don't really need the OSSC if you have a Datapath card and are capturing from VGA sources (just use a DVI-I to VGA adapter). I would stick to 60Hz output though, makes life easier for …
Re: Windows NT 4.0 running on real new hardware (Ryzen 3900x) [updated]
Posted on 2021-11-05, 11:23
The UniATA driver should allow the onboard SATA ports to be used by NT4. PCIe's architecture is more hub and spoke vs. conventional PCI. There are a ton of PCI-to-PCI bridges visible in legacy OSes to deal with it. I wouldn't be surprised if the bus numbers have some relation to IOMMU grouping seen …
Re: Windows NT 4.0 running on real new hardware (Ryzen 3900x)

I managed to get NT4 running on Core2 era hardware (PCIe video and SATA) with no problem. I followed the multiple step process to slipstream SP6a+post SP updates along with the UniATA driver onto CD. Having UniATA seems very important on AHCI only systems. The NT4 kernel is much better behaved on …
Re: Optivision OPV9100 MPEG2 decoder for EISA bus

SGI used EISA in a few systems. https://techpubs.jurassic.nl/manuals/0650/dev … _html/ch18.html Looks like some custom glue logic to connect the Intel 82350DT EISA chipset to the CPU bus. There is a really REALLY amusing error in that link though.

The Adaptec board may not work properly with the HiNT Caesar chipset. One of the things that was cut out was properly bus mastering support which the 2740W uses. The older AHA-1740 would work with CFG file changes, check old usenet posts.

My P5A refused to run a K6-2 550Mhz CPU for some reason. Meanwhile the P5A-B I had ran it just fine.
Re: Recovering data from old DDS3 tapes; I have a tape drive, but usability questions

I've written DDS2 tapes using a plain old DDS drive and it worked fine. The header your dump shows is not TAR though, it was likely created with Arcada/Seagate/Whoever owns them today Backup Exec on Windows.
Re: BIOS Wanted for A.I.R. 486EI EISA motherboard
Posted on 2021-09-04, 23:45
That's likely the latest revision of the 486EI. Chips are dated 1994-95 for the most part. The real question is what revision/core BIOS did the unbranded AIR 486EI boards come with? Also checking ebay, there appears to be a DEC OEM motherboard with the SiS 406/411 and a Phoenix BIOS (also too old …

The AMIBIOS on the NiCE and Tyan boards does support 256MB albeit with 16x16MB 30pin SIMMs. The image uploaded is using the 06/06/92 HiFLEX core, so too early for DX4 support.

Modern Linux should still support something like a dirt common AHA-2940 card (AIC-78xx). DDS3 is pretty new as far as DAT drives are concerned. If you have a machine with PCI slots, throw it in and try a modern Linux distro. Hopefully your tapes are direct TAR, makes restoration easy.
Re: My Ultimate VL/EISA 486

DX4 CPUs work fine on the NiCE SuperEISA and Tyan S1437. I'm running a DX4-100OD on both. You aren't getting writeback L1 cache on them though as the chipset doesn't support it.

I have really really bizarre issues with the S1437 and it's keyboard controller. If the machine is not in v86 mode (running something like EMM386 or Windows) and I try to run SimCity 2000, the machine starts beeping via the PC Speaker and locks up. With EMM386 loaded (or another keyboard controller …
Re: Asus P5A-B - ATX case solution?
Posted on 2021-08-24, 16:38
I had a P5A-B in an early ATX case for ages until I replaced it with a P5A (yeah, I bought BOTH versions new somehow). I don't recall any problems mounting it. The bottom two screw holes should line up with an ATX and AT case. The middle screws (one under the CPU socket) may or may not be present on …

You should be able to tone these out with a multimeter. Since the Game port has +5v pins, look for those first and mark them off so you don't connect power to something that shouldn't have it. Normally audio headers have one row that is all grounds while the other row is the signal pins.
Re: GA-486SA: RARE EISA + VLB, or proprietary local bus slots?

Those slots are almost certainly VLB. I have two different SiS 406/411 EISA boards here with VLB, so it was a common combination.
Re: Looking for EISA configuration utility for this EXP4409 motherboard (and any documentation too)

When the machine POSTs, what is the AMI BIOS string shown on the bottom left corner of the screen during memory test? This will ID the company that made the board. You may want to try the generic Micro Computer Systems configuration tool (CF.EXE) as well. Looks like it may be a DataExpert board: …
Re: Looking for EISA configuration utility for this EXP4409 motherboard (and any documentation too)

That board uses the HiNT Caeser Mini-EISA chipset. The implementation is limited and incomplete with regards to bus mastering. You should be able to find the configuration tools and config files here: http://66.113.161.23/~mR_Slug/EISA/ This should work with the AMI ECU to detect the board: http:// …
