Hello. I found out just now that the programming for accessing the disk using INT13h looks like assembly code. I don't understand the topic and I wonder if anyone knows of a way to help me understand something about addressing. Given a VM with MSDOS 6 instantiated; Does the virtual BIOS & PATA …

Yes, it is. But you need Windows 95 B or C. When you open a command prompt (command.com) and you type "ver", what do you get?

No wonder. As far as no T&L is used, the TNT2 Ultra clearly should beat the GeForce 2 MX. I mean, you compare a king of the hill from a not so far former generation with a low end graphics card!

Oh! Since an Am486 DX4 (N)V8T behaves like a 3,45 Volt DX2 with L1 cache in write through mode, you need a different jumper setting for a write back enabled DX4 like the Intel &EW.

I disagree. So I agree with maxtherabbit (last post at the moment): Especially the Compaq QVision 1024/E is good in DOS. I made some benchmarks https://www.vogons.org/viewtopic.php?p=838387#p838387 I don't think this throughput is possible with an ISA card. Thanks for the benchmarks. I'm impressed …

With your 64 kB of L2 cache, obviousely operating in write through mode, please do not install more than 16 MB of RAM. Otherwise there will be an uncached area in your RAM with that small amount of cache. Note that that dirty tag ram will be quite different from your other SRAM chips.

There are several things that can happen on old computers when touching a technical border of such a system. From 120 GB to 160 GB there is a border at 137 GB (128 GiB). It's the so called 48-Bit-LBA border. Earlier systems had borders at 32 GB, 8 GB, 2 GB and 504 MB. You may feel strange behaviour, …

You can add another primary partition and install another operating system there. However, you have to extract it's boot sector then, save as file on the windows 2000 boot partition, and to include it in boot.ini - you have a boot menu then. For operating systems like DOS the new partition has to be …

Ah, that's easy. Some newer supplys have 24 pin connectors that can't be split to 20+4 pin connectors. So if you use a 20 pin connector on the motherboard, a 24 pin supply connector won't be blocked by capacitors. You need a 24 pin connection when that one +12V wire from the supply does not have …

You can use a 20 pin connector. But I recommend to leave the space next to it free, at least from big capacitors like in your pictures. But a 20 pin cable will also fit into a 24 pin connector on the board. It won't make any problem as long as you have same power connections shorted. 24 pin became …

Question about the cache. Did someone here test how the speed scale with different cache setups? more cache - faster transfers?
