Re: CF-Card DMA issue with my AMD K6-2 500 MHz SS7 Setup

That’s great. That means Windows would be happy to store the page file on the CF Card. I wonder how long the CF Card would last with having Windows run on it with all the write to disk operations. Depends on the CF, the version of windows, amount of ram, your usage pattern, etc. If you were using …

Getting UDMA working is pretty important for a pleasant computing experience for hardware from that period. Enabling UDMA requires cooperation between the IDE controller, the IDE Driver, and the IDE storage device. I'll assume you want to stick with your current onboard IDE controller. Which driver …

That actually looks pretty decent, like they actually took some care in fabbing it, Ive had some horror parts come out of China buying only based on the picture and price. How much did this little part cost ? I have a few and they've been pretty foolproof. I use one in my Socket 7 mITX system. It …

Re: Fastest SD card converter for IDE interface?

Pretty much the only SD to IDE (or CF) option is the FC1307 chip. It won't even saturate ATA-33 (33MB/second). Adapters using it are ubiquitous. There was at least one other option, the INIC-2051 chip. Good look finding an adapter that uses it. It is faster than the FC1307, but is less compatible …

Short-lived? PPro was introduced in 1995 and superseded by P2 in 1997. That is as long as Intel's flagship as the P2 managed and longer than the P3. The reason PPros are so rare isn't that they were on the market for a short time, it's that they served a specific very expensive niche, and did not …

My thanks to everyone who tried to help me! It finally works now, turned out the problem was the cheap chinese CF card (or/and its huge size). Today I got a 128MB iPQ (or something like that) and a 256MB Sandisk and they were both instantly recognized correctly by the BIOS and the PC booted without …

I see, what baffles me is that as master and only drive it worked fine. Today I got a 128MB one and will be picking another 512MB one so hope you are right and the size may be the problem. So is it better to keep LBA disabled in BIOS as it was before? Could I use FreeDOS FDISK just to partition it …

Unless you are using DOS 7.1 (aka Win95b or newer) you will likely have a hard time using drives larger than 8.4 GB. Did you try removing the master/slave jumper on your CF adapter? Did you try using a blue 80 conductor IDE cable that supports cable select, putting the blue block on the mobo, the …

Understood, the 256MB CF I have on the way to me is a Sandisk and I assume it will be a bit older than the 16GB I have now. I will read on EZ Drive, thank you. Not sure about XTIde, I think you need a network card for that? Have none around. But I am going to try the two tools on the PC itself to …

I don't think this is a 3.3V issue. That CF adapter doesn't do 3.3V and it is unlikely that this CF requires 3.3V, but I don't see the CF make & model posted in the thread so I can't be sure. Can you post some info about the CF? Trying to run a CF in a master/slave configuration can be a difficult …

Intel was messing around with Rambus (google 'Caminogate' for an example of Intel stuff you want to avoid) Avoid? Rambus P4 systems sell at a significant premium these days. You'd be lucky to have one. But ironically, FDIV Pentiums are also more valuable than their fully functional replacements. …

VIA chipsets were generally good. The issues that I had were often related to: 1) Drivers: Intel invested more resources into driver & software development and sometimes it took VIA longer to get the bugs & quirks out of its drivers. 2) Power: Intel left the AT platform early while VIA got to deal …

The 256MB one is really strange. Possibly you mixed up something, or the markings on the chip are completely fake. The HYB25D256800BT-6 is a DDR chip which requires 2.5V , so the DIMM should be keyed completely different from the (SDR) SDRAM DIMMs. 2.5V DDR memory only has a single notch, and …

Right, just to be clear, if you put a CPU rated for up to 25MHz in a motherboard running at 10 MHz, the CPU will run at 10 MHz. But in the 286 world, there were never any voltage or cache changes between the different versions, so thats all pretty simple. But changing the clock speed of a 286 …
