What is the advantage of a 8087? Are there any games that use it? More for completeness than anything - but there are a handful of flight sims and I also have an old CAD program I want to mess with designed for XT class machines. One game, which I do have on the Tandy that supposedly does use it is …

http://www.elhvb.com/mobokive/Archive/Octek/4 … DCA2/index.html Most 486 motherboards used 28-pin BIOS chips. A 27C512 EEPROM should do the trick, but confirm first by checking the size of the BIOS file that is online.

Here's a link to where the BIOS files are stored for the PVI-486SP3, but you can Google this motherboard as well. The BIOS files are scattered all over (including here on Vogons in older posts): ftp://ftp.asus.com/pub/ASUS/mb/sock5/486sp3/ Just take note of your motherboard's revision and chipset, …

I'm pretty sure UOSP 2.1a doesn't have the USB mass storage drivers in it. If somebody can confirm that it does, I'll remove the section advising the separate installation. No, it doesn't. However, the Unofficial Service Pack 3.x and later versions do. Please just note that it must be installed ( …

That makes sense to me - I did notice the lack of a BIOS, but I thought nothing of it due to my lack of experience with stuff like this. I unfortunately don't have access to a programmer (or have an EPROM to program). That's a rather generous offer, and if you think that that might get the board …

You can either try the above method or, just edit the ctpnp.cfg file under your Windows directory (if you want to use different resources to what Windows is using). The default is A220 I5 D1 H5 P330 T6 - these are also what you specify in your Autoexec.bat file next to your SET BLASTER= environment …

Regarding XT keyboards, I see this question all the time. You don't have to buy an XT keyboard! You can just get an old AT keyboard because most of the early ones had a PC/AT or XT/AT switch on the underside. I even have one from the early nineties that has this switch. I recently managed to find a …

Based on your original list, for a 386 DX-40, you can't go wrong with either an ET4000 or the CL-GD5424. I favour the ET4000 a bit more.

Is there any particular reason that you need both DOS 6.22 and DOS 7.1 (which is what is "bundled" with Windows 98SE) on the same PC? Why not just set up a start menu configuration under Windows that will allow you to boot into either DOS 7.1 or Windows? Refer this topic: http://www.vogons.org/ …

Make sure the settings in your setup menu matches the emulated settings of the sound card under DOS (DMA, IRQ, etc.). The default settings are normally A220 I5 D1 H5 P330 T6.

Provided you find the correct installation CD, when you run the installer under Windows, it will ask you whether you want to install the DOS drivers. If not, then you know that your installation CD doesn't contain the DOS drivers. You can install it manually, but that's a different story. I still …

Yes, I would recommend you rather try Windows 98 SE, with the Unofficial Service Pack 2.1a. The later Service Pack (3.x) also contains a USB stack driver. I normally just extract the USB stack separately and install after I've installed Service Pack 2.1a.
