Stuff from around the 386 and 486 "era" of PCs are some of my favorites.  I have no clue why, but it is.  This topic is for memories of these computers, discussion, help, etc.

My love of these computers is mostly rooted in childhood memories.
When I was quite little my grandparents bought themselves a computer so they could type things up.  It was a budget model Packard Bell (Legend 204cd), 66mhz 486/DX2, 8 MB RAM, and a 518 MB hard drive.  A bit later, I started checking it out and found the educational software CDs that had been packaged with it.  I taught myself how to get into DOS and run them, quite surprising because my only computer experience before this was drawing pictures on my parents' Mac Performa 600.  Later, I stole a game disk from my cousin's house, namely Lemmings (my favorite PC game, hands down), and a CD of some FMV game called MegaRace.  I popped them into this computer and had a blast, fully fueling my initial interest in the computer.

As it was the only computer I was regularly able to use until my family finally bought a useful computer in 1999, I learned basically everything the 486 could do.  So, at age seven or so, I was essentially my grandparents' tech support, fixing their every problem.  I was also very curious and attempted different ways to free up hard drive space to add more stuff... including deleting what I called "blank files" (which were actually Windows DLLs) and then freaking out when Windows 3.1 would no longer boot.  I managed to hunt out the restore disc and reinstall it before anyone noticed... Tongue

Anyway, since then said 486 has now fallen into my posession.
Here's an old pic from when I first got received it from my grandparents.  At this point, after essentially a decade of stuff, I had done a lot to modify it, including installing Calmira on Win 3.1 for the Windows 9x taskbar I'd discovered I liked.  Looking back, I imagine they didn't like how I also controlled their wallpaper and treated the comp like it was mine Tongue

I've wiped it clean and set it back up to clear out years of random stuff and have started going nuts on DOS games and audio.  There are tons of games I never experienced and I am now playing fervently.   Plus, I found some retro FM trackers to mess with synth music.  One of my favorite things about computers from this era are Adlib cards and their many imitations.  The synthesized awesomeness of Adlib music just rocks.

There's a lot these computers can do that new ones can't, mostly in the games department... I just love them.

That leaves me with a question.
My interest has taken off to the point where the hard drive is just way too small (518 MB).  Should I try and find a hard drive that works to replace it, of which one attempt has already failed (tried installing a salvaged 8.4 GB hard drive from a computer in storage, and the BIOS can't handle the geometry of it), or would it be easier to just locate an ISA ethernet card and create a basic shared folder between it and another computer?

Anyway, post your memories, ideas, and questions about these era PCs.  (Hey, it's discussion material.)

I love the 384/486 era too, mostly because I "came of age" regarding computers during that time.

I use an old 16 MHz 386 with 4MB of RAM for playing old DOS games (as seen in action here).  About four years ago, I put an ISA 10Base-T Ethernet card in it that I had floating around.  I now use that card, coupled with a Microsoft MS-DOS networking client, to pull files off of my modern computers when I play games.  That way, I can delete games I no longer use off of the computer's paltry 140MB HD and not lose them; they're only a network connection away.

If you need more info on the Microsoft network client for MS-DOS, I'll look it up for you.  As a tip, you have to install the IPX protocol on your new Windows computer (I use XP or 2000) for it to work.  I created a network share directly to my DOSBOX pseudo-drive directory so I have all my old DOS files at hand in either place.

Keep in mind that 10Base-T is too slow to run most games real-time over the network connection.  You have to copy them over first, which can take a long time depending on the file size(s).  Or you can run them over the network and wait for them to copy into your computer's memory, which can take a looong time.

---

Now, there's the other option: upgrading the HD.  Your BIOS might be able to handle 1 or 2 GB HDs, but you might have to partition them in 500mb increments.  I forgot what the FAT16 file system's maximum volume size is (2GB comes to mind), but that definitely comes into play.

I'd like to upgrade my 386's HD, but I've never gotten around to it.  I've got plenty spare IDE drives that should work, but I haven't tried testing its limits yet to see how big of a drive the 386's BIOS can handle.

Anyway, let us know what happens.  I'm glad to see people still playing with MS-DOS computers these days.

I was trying to trick out a 486DX-2/66 system a few months ago and I hit that ~520MB barrier. BIOS acted like it was going to handle all 4.3GB but FDISK (tried Win95c, Win98SE versions) wouldn't go along with my plans. FAT16, FAT32.. no luck in any partitions bigger than 520MB. I figured it was a hardware limit. One thing I didn't try was multiple 520MB partitions, though. You're right about FAT16's 2GB ceiling.

I vaguely remember some low-level Western Digital tool that came with my massive 850MB hard drive back in '94. It would load before DOS and work its magic so I could access more than 520MB in DOS, even though my little IBM PS/1 didn't know any better. I can't remember the name of the utility, but something like that might work in his case.

Anyway, nowadays I cheat! I've got a socket-7 motherboard with 128MB SDRAM, a Pentium 166 (by design, so I don't have to patch every Turbo Pascal game/program that breaks when the CPU is >= 200MHz), a 40GB 7200RPM UDMA/33 hard drive, a 16X DVD-ROM, 80-conductor IDE cables, a 10/100 NIC, a real ISA Sound Blaster 16, and a completely under-utilized 3DFX Voodoo 3 AGP video card. I run Windows 95c because it makes everything easier (separate autoexec.bat/config.sys files, networking, memory management, if needed). Right now I don't even have it boot to the GUI and I usually only load up Windows when I want to transfer games over the network. FAT32 support lets me access all 40GB of the hard drive so I can pack it full of games. Very old DOS games still run too quickly, but most are fine, and the faster hardware speeds up loading times. With that video card I can start to dabble with early 3DFX-supported DOS/Windows games, but there weren't very many good ones. Grin

EDIT: Western Digital EZ-Install is the program that allows you to add larger drives to older systems.. if you have a WD drive. It might be bundled with their Data Lifeguard Tools for DOS now. Here's a link to a PDF that I found. It sounds like EZ-Install has an "EZ-BIOS" component that does the real magic:
Quote
EZ-BIOS is code that installs on the boot sector of the hard drive if your system BIOS does not support the full capacity of your hard drive. EZ-BIOS helps your system overcome the 8.4 GB, 2.1 GB, and 528 MB barriers.
