Recall that new Win3.1 video driver that we looked at recently? It just keeps getting better and better. I reported an issue with network sharing and "green lines" on startup a few weeks ago, and it is now fixed! I decided to build the driver from source, let's talk about it! 🧵
Image
The process to build the driver is nicely documented! I downloaded the Win16 DDK and placed it at C:\DDK31 in a DOS6.22/Win3.1 VM. I also installed Microsoft Visual C++ 1.52c, and grabbed a copy of EXE2BIN from FreeDOS. Image
Image
Image
Image
From there, in DOS, I edited the C:\MSVC\BIN\MSVCVARS.BAT file as directed and ran it. Okay, we are ready to build! Image
Image
First, I built the VBESVGA.DRV file. It's a matter of navigating to the VBESVGA directory (that you place within the DDK directory structure) & running "make". One step failed, I just ran it by hand & it succeeded (not shown). Once built, I copied the driver to C:\WINDOWS\SYSTEM Image
Image
From there, we build the 386 Enhanced Driver. You navigate to the VDDVBE directory that you place in the DDK, and run "nmake". When done, just copy the driver to C:\WINDOWS\SYSTEM. Image
Image
At this point, I just launched Windows since I had already configured this new driver before. But if you haven't, the steps to do such are pretty straight forward, you just need to edit C:\WINDOWS\SYSTEM.INI accordingly. Image
And that's it! I love seeing the progress on this driver. If you haven't seen it yet, you can find it at . I presume new file versions will be posted soon that contain this fix, I was just impatient 😂. Thanks for following along.

Let's talk about my newest PC acquisition, which might be the most budget build ever 🤣. But there was a reason for buying it. I'll cover that... along with a Windows 95 installation, in a 🧵. Let's go! Image
First, why did I buy this? Well, the plan was to do a case swap with another system I had, which had some strange "fit" issues. However, that planned got smashed... literally. So, I thought we might as well explore what's left of this PC!
This system has a PC Chips M748MR motherboard, an Intel Celeron 400 MHz processor, and 16MB of RAM. Yikes! And of course the case is nothing fancy, but is nostalgic for me. But yea, this is the most budget build ever, for sure! Image

I just watched a video where YouTuber Action Retro set up a web server on a floppy disk using ELKS (the Embeddable Linux Kernel Subset). I thought, I have to try this for myself! Let's talk about it briefly in a 🧵 Image
Image
So, first of all, what is ELKS? It's the Embeddable Linux Kernel Subset, and it will run on a wide range of hardware, including 8088 systems. Pretty wild for a modern product! If you want to read more or try it out, GitHub repo is here: github.com/ghaerr/elksImage
Alright, let's go. I need to choose a system that will support the networking for ELKS. Turning to the Wiki, as of right now, the network cards supported are NE1000, NE2000, Western Digital 8003, Western Digital 8013, and 3com Ethernet III (3c509). My 486 DX4 has a 3Com 3c509! Image

I got a new DOS file transfer toy! Now, these have been around since the dawn of time, but let's talk about it: a MicroSD to LPT Printer Port Adapter. We'll give it a test on my Compaq LTE 5400. Time for a 🧵 Image
Image
First, if you are interested in reading about these, there is a thread on Vogons! Included in that thread is where I found the DOS drivers for it, you can go here for that, and to read about this device! vogons.org/viewtopic.php?…Image
Also, here's a few more perspective shots of it, captured from different angles. Image

I got some Xircom PC Cards in the mail today! Let's test them out and see if they work! 🧵 time! Image
Image
Image
First, if you missed it, a few days ago I posted this. Given what I have paid for these in the past, I was very pleased!
And speaking of the past, here's what I had before today: four cards. These Xircom RealPort Ethernet 10/100 cards are great for getting a laptop without Internet connected to a wired network! Image

My holiday break is quickly coming to an end. So, I think it's time to power on the retro PCs that I have yet to power on recently. I am sure this will go flawlessly 😂. Let's do most of this, in real time, in a 🧵 here! Image
Image
Image
Alright, you've already seen the first three. My trusty, original 486DX4/100 powered right up, as did the Packard Bell Multimedia 601 Pentium 233 MMX Image
Image
Image
Image
How about the Kehtron 486 DX/50? Weeelll.. the front seven segment display needed reconnected (I really should fix this permanently), and the sound card was being a pain, but I moved it over one slot and it is now working! Image

The challenges and solutions in retro computing never cease to amaze me, and today's project is no different. Today's goal was getting working storage in this AST Premium Exec 386 laptop. And fortunately, somewhat against the odds, I found one! Let's talk about it in a 🧵 here! Image
Image
So, anyway, the issue I had with this laptop is that the original 20MB 3.5" IDE hard drive had died. I thought "no problem, I'll pop on eBay and get one." Except they are scarce and expensive. I picked up two 120MB drives and one 40MB drive. None of them worked. Image
Image
In the past, I had also tried a CF card. I could get the CF cards to a point where they were accessible, but when I go to boot, I get a blinking cursor.. and sometimes a "non system disk or disk error" a few minutes later. Tried multiple CF cards, same result. Image
