Ubuntu 18.04 hasn't dropped AGP support - I said that the Unity desktop environment doesn't appear to work with AGP cards (when I tested it on my P4 Prescott - 32-bit - 7900GS). It worked with the GNOME3 environment in 32-bit though. For all I know, it is just Unity which doesn't work with AGP …

The rule of thumb is, if they can relocate, then load them last. If they cannot relocate, then load the one that requires large runtime memory first. Unfortunately, there is no easy way to tell how much runtime memory it really needs, so this is trial and error, or you can base on the actual file …

That just means that the largest contiguous UMB isn't large enough. 20~30KB isn't very large for TSR whose resident size is 12KB. Many TSRs need significantly more memory for runtime before they shrink their memory footprint upon staying resident. if you could get 64+ free UMB, then perhaps both …

I'm currently running FreeDOS 1.3-rc3 on a legacy-focused system. While I can easily attain more than 600KB of conventional memory, I noticed some TSRs that I'm using don't load high even when there appear to be plenty of upper memory for it to be resident there. A good example would be DOSLFN . The …

I still think the USB mouse needs to be able to understand PS/2 protocol somehow. The Legacy USB Support option appears to mimic what a passive USB/PS-2 adapter would do, as the behavior I observed on a same USB mouse is consistent, when I plug it directly to the USB port or when I plug it to the …

Sorry to say but you have some misconceptions: The most important one is that USB mice emulate PS/2 some way. The truth is USB mice NEVER 'emulate' PS/2. Your motherboard's BIOS has to emulates PS/2 for USB mice that do not implement PS/2 protocol natively. So in your list problem 1. is strictly …

You might want to try the workaround described here https://www.vogons.org/viewtopic.php?f=7&t=76481 as the root cause is likely similar . Some USB mice don't work correctly when operating in PS/2 mode (through passive adapters), and the more "features" your mouse have the worse its compatibility …

I think if you use a modern HIMEM replacement, such as XMGR, HIMEMX (as well as JEMMEX), you would be able to access all the RAM. This applies to PC-DOS 7.0/2000 as well. As for QEMM (9.x), apparently it uses its own XMS manager and that appeared to have a soft limit of about 64MB and a hard limit …

TL;DR: Having SF2-capable sound cards is not necessary for soundfonts nowadays, but such sound cards can improve responsiveness if your CPU is relatively weak. EMU10Kx (Live/Audigy) and EMU20Kx (X-Fi except Xtreme Audio) are the last few cards to have hardware synths. However, it seems only the …

You can't use DDMA on any ICH because it was never implemented there. Up to ICH5 has PC/PCI support but that requires connecting a few physical wires (if both the board and the card have the SB-Link connector) and doesn't work out-of-box.

Windows 7 can also be rearmed up to 3 times for a total of 120 days. There are no restrictions during this period and you're considered genuine. Not sure where you got the license from... you probably need to ask the dealer if the key doesn't activate.

By default, PCI cards don't work at all under DOS with AMD chipsets. For 700-900 series chipsets, you can load the TSR but it'll have no effect. Games won't even detect the presence of Sound Blaster, so even synths won't work. The situation is worse than ICH6+/nForce southbridges. On the other hand, …
