Trying to upgrade a board.

Board is a Micronics DX25, discrete logic board. Stuck a Dx33 in it and changed the crystal to a 66Mhz crystal and it simple won't boot, post card displays no numbers. I put the 50mhz crystal back in and it posts just fine. Never seen this happen before. The boards seems to be mostly PALs and …
Hardware failure.

Ugh, I am really starting to not enjoy this hobby. I realize this stuff is old. Much of what I own is 25-35 years old. I realize stuff will begin to fail with time, but goddamn, it seems that over the last 12-18 months I have had a massive upswing in hardware failure. Is it just me, or has anyone …

I just did that and it did indeed work. Thanks for your help. In the end it didn't matter because the card will not accept the drivers for Windows 95. I may trie forcibly installing them later but I'm too disgusted with this and other issues at this point. Such is this hobby.

I recently got one of the Aztech Waverider Platinums with the WaveTable, and upon downloading this file here , I discovered that the image for the Music Workstation CD seems to be corrupt. It will not open as an archive, nor will it burn to a CD. What are you using to burn the CD image ? I just …

Debating on what to put on a Pentium 66 machine, and was wonder how much slower 98 is vs 95.
Has anyone ever compared 1MB and 2MB operation on an ET4000W32/P series?

Just tried this today. Nothing fancy, just informal testing of the Phil's Dos benchmark programs on two different machines. One was a Pentium 66, Batman's Revenge with 256K cache and 32MB 60 ram and Phoenix Bios, the other a Micronics branded Intel HX with an Intel 233Mhz cpu, 64MB 60ns ram, 512K …

Again, does this bug affect the 5429 and the 5434?

What real world games/programs does this affect? Does it affect later revisions, such as the 5429 and 5434? Does it affect both ISA and VLB, or just one or the other?

Hi again Vogons. I have long since gotten this going, but now I hit a new snag. I cannot get this thing to post with anything other than my VGA cards. For EGA, I have an American Microland HEGA480, and an Emulex Persyst EG-8. The XI8088 turns on and does its chime, but nothing appears on screen when …

Aren't 386 BIOSes usually 32K? You may to dump it as a 27c256, using the above mentioned methods. Wouldn't hurt to try both, I don't think.

You don't have have the ISA bus speed set too high for the graphics card, do you?For 40Mhz, you have an 80mhz crystal. So CLK2/5 = 16mhz, clk2/6=13.33Mhz, clk2/8=10Mhz, ect. My fastest ISA graphics adapter doesn't like 16Mhz, and will give graphical errors.

Whatever method you use to do this, make sure they are compatible. Some BIOSes are for subtly different variations of what is otherwise the same hardware. I got bit by this not too long ago with a Tyan Tomcat. Had an award, changed to the AMI, now the board will not use the hard disk or floppy.

So I had two of those flash rom chips, because I accidentally ordered two. I decided, since I had nothing else to lose, decided to get a fresh copy of the BIOS and a feshj copy of uniflash. I hotflashed the chip, using the 128K image, just like last time, and the Xi8088 actually posted this time. …

I wrote the 128K image in another motherboard. Right now I have set it to the side until the replacement 82c84 is here, and I made sure it was a proper CMOS version.

I just finished building one of these. Getting nothing at boot. No beeps from either the internal speaker or external, nor any video. nothing. I am reasonably sure my backplane is not the problem. The only signs of life I get are the keyboard lights flashing on power on. The power LEDs work at both …
