I will add to this by pointing out that, if possible, get a board with a CR2032 battery on it. Anything with a soldered battery has the risk of having been damaged by a leaky battery. This damage can be obscured in eBay auctions by providing poor pictures, so be mindful This auction is a good …

Mine was a TI TMS27c512. You could try USB 2.0 ports if you have any on your system. According to the pictures on the site provided above, it looks genuine.

Hi, everyone, Expect a bit more action here now that I've finally gotten some bigger things taken care of! Earlier in this thread, someone requested the BIOS dump for the Number Nine #9GXE64 Pro VLB card. Elsewhere, someone needed the BIOS for the motherboard, the QDI V4P895P3/SMT v5.0. So, they're …

Hi Parni, Here is the BIOS file from mine! It is from a TI TMS27c512 read using a TL866II Plus. This is my first time using the programmer, so no guarantees. I am seeing the Name and Date of the BIOS in the .bin, though, so I think that it's good.

Okay. I'll try to get the BIOS uploaded in the next couple of days. Check my signature for my 486 build log. I'll get info on the RAM at the same time. I also have the v5, so the BIOS should be golden for you!

I'm not seeing anything in here about the PSU. I see NOS, but that doesn't mean anything at this age. The leaky/bulged capacitors on the motherboard need to be replaced, but don't discount the PSU as the primary problem unless it is definitely working in another machine! Anything modern should be …

Your jumpers (in the picture on the first page) seem to match the ones I have configured for a 486DX2-66. Can we please see a full picture of your board as you're testing it? Is it on anything or in anything? How is your CPU oriented? How are the leads of the chipset? Are any bent and making contact …

You absolutely need -5V for CMS on an SB 2.0. There are adapter cables that can generate it when going from ATX to AT, but I can't find anything on ATX to ATX. It is a very simple circuit with an LM 7905 Voltage Regulator, so if you really want to do it this way, you could make one yourself. CPU …

it’s NOT about which CPU is faster. You already know which CPU is faster by the MHz rating. It’s about which CPU will allow for the play of the most DOS games in good quality. Sure you want the fastest CPU but you also want to be able to down clock it for CPU speed critical games. Down clocking by …

If what you want is good signal-to-noise ratio.... What to avoid: - early SB 16 For what it's worth, an appropriately configured SB16, early or otherwise, can be respectably quiet. From my highly-disappointing thread that touched on this very subject: https://www.symphoniae.com/soundcard/RMAA/ …

This is referring to the sticker on your motherboard's BIOS chip. At the image in the link, at the bottom right of the image (upside-down) to the right of the CMOS battery, the sticker has an 7-digit code (103C701 in the picture). http://www.amoretro.de/wp-content/uploads/fic_486-pio2_486_pci_ …
