Time for another OS install on the eMachines T2341. This time, it's Windows NT 3.51. Prepare to be underwhelmed by this install šŸ˜‚. I'll explain more, let's do a 🧵 Image
Image
So, similar to other NT installs, I copied the contents of the i386 directory to a FAT16 drive partition. Running winnt /b, we are able to do a diskless install from there! Phase 1 of 3 completes pretty quickly. Image
Image
Image
Time for the "DOS-based" portion of the install, we'll call it Phase 2. During this part, we get to choose the install location and get to choose to convert the partition to NTFS if so desired. I elected to do just that. Image
Image
Image
Now on to Phase 3, the "graphical" install. We get to choose what to install, and I also set up my network card. I needed a drivers disk, which I found on the Retro Web. Here's a link for the interested! theretroweb.com/drivers/840Image
Image
Image
Image
During Phase 3, we also get to choose the video mode. Unfortunately, the stock S3 drivers won't work well, and there aren't any good drivers for a S3 ProSavageDDR for WinNT 3.51. As such, you're best to press "Cancel" here, or you'll end up in video mode hell otherwise. Image
Image
For the curious, I did try a few different options for video drivers, including Windows NT 4.0 drivers, and also drivers for an S3 Savage card, but that is NOT the same as the ProSavage, so it didn't work. And as for sound, we didn't even try to get the AC'97 audio going. Image
Image
So, where does that leave us? Well, at 640x480x16 colors, with no audio, but at least we have network! Fair to say, this Athlon XP 2400+ system was NEVER designed for WinNT 3.51. But we had fun anyway... right? RIGHT! Thanks for following along!

Okay, let's look at one more retro item today: this ISA to USB interface card with an M-Systems Disk On Chip module! Can we use this little device to boot a computer? Absolutely! We'll test this out on the Pacman PC. Time for a 🧵 Image
Image
First, where did I get this, and what does it do? I picked this up from AliExpress, and this device basically lets you access USB drives from DOS systems. And it does support boot ROMs like the M-Systems Disk on Chip. We'll be using that today. Image
Let's look at some of the settings. We have a jumper to change the I/O address. Another jumper specifies 16 bit or 8 bit system. And the jumper in the middle? It's a mystery. The back of the board has some writing in Chinese that basically says "this end faces PC rear" Image

Recently I picked up this SMC network card, that supports network boot via a boot ROM. I spent some time with it, and we had some misadventures together. But it did give me a chance to test out my new POST card too. How could all of this be related? Time for a 🧵 Image
Image
First of all, let's take some time to admire the property sticker on the back! This card was allegedly property of America Online at some point 🤣 Image
Okay, so I got this SMC Ethercard Elite 8216T (say that five times fast) installed in my Pentium 233 MMX. I was able to pull up the boot ROM configuration page, but savings settings would freeze. That would be a bit of a metaphor for this card... Image

Hooray, my PS/2 Model 70 386 is fixed! No more issues with the system freezing on powerup when a Microsoft mouse is plugged in. How did I fix it? Let's talk about it in a 🧵 here! Image
Image
In case you missed it, I recently got a device to display BIOS diagnostic codes on powerup, and we learned that the system was getting stuck when it was testing the keyboard controller:
So, what did I do? I went to eBay and found an untested motherboard. For $35, I was more than willing to take a gamble! Image

My parallel port POST test card arrived today! Let's test out my IBM PS/2 Model 70 386 to see if we can figure out why it is not powering up when certain types of mice are plugged into it! Time for a quick 🧵 Image
Image
First, a little about the tester card. It's an AliExpress special. That said, it did get here pretty fast. I'm impressed! Image
Alright, first off, let's try this card out without a mouse plugged in. Looks like the system boots, and we land on code 0x6E. I found this awesome reference manual called The BIOS Companion, and it has this code listed as "Reset page register; boot up system". That tracks! Image

Okay, you all voted, and for NOW, we're going to put this NEC MultiSpin 6X SCSI CD-ROM into my Pentium 233 system. This drive is REALLY cool! Let's talk about it briefly in a 🧵 here! Image
Image
First of all, if this ends up being permanent, I won't be too sad. The Philips drive that was in the system is starting to look a little ratty šŸ˜…. Granted, for form over function, it is an 8X drive, so TECHNICALLY this is a downgrade! Image
Image
Also, before I get too far into this, in case you missed it, I picked up this drive earlier today at a vintage computer sale that was happening a town or two over! I did grab all of the caddies you see here that go with the drive as well!

Looks like someone about 20 minutes away from me is selling a massive Macintosh/PC collection. I think I might go have a look, just for fun of course! Some pics. 1/4 Image
