I did it! I finally did it!

Successfully brick a mainboard

Homepage was no longer online, so I had to rely on a 3rd party site. Seems like I got trolled.
But it's not the end of the world. Hirsch has a programmer and will unbrick it, next time he's around.
At least all my other boards have the latest BIOS now. Except a 440BX which I got recently. Have to undig my (only) Pentium II first.

Found one more damaged board. Floppy controller doesn't seem to work. Drive gets detected, but can't read or write anything.
Getting close to the end of the pile.

Several months ago when I built an Arduino-based Daemonbite controller adapter, I neglected to enable the optional Debounce function. That had not caused a problem. Until recently, when it interfered with the proper operation of turbo fire.

So I had to delve into the innards of my arcade machine, to rectify that.

In doing so, my movements caused the Arduino's ultra-fragile microUSB port to snap clean off the board, to my delight. I knew at that point I was facing several hours of major F'ing around, vs the quick half-hour job I had hoped. A quick plug + re-program, turned instead into a dig-out of the entire control jig for that side, fix/replace/repair, then painstakingly re-instate.

And so began today's tedious epic of being hunched over into pretzel shape, reaching into my extremely-inconvenient-to-work-on arcade machine, getting everything going again. Several hours later, and finally - at late afternoon - I've reached the point where I had initially hoped to start the day - relaxing into a game of Metal Slug X, on my MiSTer, with my Sanwa controls .... and Turbo fire working.

It didn't help matters that, like all multi-emulator systems, MiSTer has somewhat arbitrary control configuration limitations and vagaries of it's own. But hey - task complete.

I try to flash the latest version on all of my motherboards as well. But recently, I have learned that this is not always the best course of action, at least for socket 754 retro builds. Basically, using anything but the oldest BIOS halves GPU performance under Win98 on the system that I was putting together.

Due to that experience, I now always back up my existing BIOS, try to read the release notes of the new version (if available) and do a quick benchmark before and after flashing to see if there's any performance loss. Better safe than sorry.

Over the last few days I did some BIOS modding for my Diamond Micronics C400 motherboard, which is identical to the BCM QS440BX. While Diamond stopped shipping BIOS updates at version 1.06, BCM continued to improve the BIOS for their board - but only for the later revisions with a 2 MBit flash chip. Seems they didn't want to bother with the space constraints on the 1 MBit chip anymore.

Since Diamond used the 1 MBit variant, I could not use the much newer and improved BCM BIOS version 2.10 on my board. So I salvaged a 2 MBit chip from another (dead) Slot 1 board and did a hot-flash, which to my surprise worked on the first attempt.

While I was at it, I modded the BIOS:
- Used the patched BCM QS440BX image from wimsbios with 128 GB HDD support as a base
- Inserted the full-screen logo (Diamond/Micronics) that I had extracted from the original C400 BIOS image
- Created and inserted a Diamond logo to replace the EPA logo
- Added various microcode updates so I can for example run my Tualeron 1400/100 in a modified Slotket
- Modified the BIOS string to show the Diamond C400 name instead of BCM

I know this is old but do you happen to have that modified BIOS at hand? I have the same board and would like to update the bios with the hotflash method and a 2mb chip, and I don't feel confident enough to modify a BIOS myself

Sorry if I'm necroposting quoting this btw but I'm not allowed to send DMs yet and I think it's the only way to reach you
Thanks!

Had one of those nightmare/comedic repair days, inside a far-far-too-cramped, awkward arcade machine of my own making.

One of those days where you begin work (slash, gaming), but realise something is not working right. So I fix it, and re-assemble the machine. I then realise *idiot* I've forgotten to re-plug something trivial inside the machine. So I open it up again, plug the thing in, put it back together again. Sigh! Sigh the First, as it happens.

Then I begin work (slash, gaming) again, and immediately notice that now audio's gone. What?! Awesomely, while doing the previous fix, in this nightmare cramped machine, bent over double with my arm shoved up this cavern of arcade doom, I've accidentally pulled a connector out from deeeep in the innards. 5 parts need to come out to even *get* to the socket for replugging. This is *at least* twice as annoying as the initial fix was. Sigh the Second. His reign was not short, and also, not sweet.

But fiinally it's done. And so I game.

Hey. One button's not working. One BUTTON'S NOT #%&$*^% WORKING. Doesn't take long to realise that Fix 2, which was caused by Fix 1, has itself caused 8% of Fix 1 (that is, one pin) to come unstuck, and oooohh yes, it's time for a visit to Fun Old Aunty Take-Apart again, for the 5th time this day. Grrrrr!

This time, I thoroughly test every aspect before putting the screws back in. While glaring harshly at the machine, just daring something to not work. This repair is going to get veeerry interesting, Will Smith style, if this farce goes on any longer. But at last, I'm here, looking at the attract screen finally. All the controls are good. Picture's good. Audio works.

Just in time to go and do the house work and meal preparation! 😁

Always reminds me of this clip with Hal trying to replace a lightbulb.

Hahaha!, nice one. Yes it was exactly that. With the addition of the Benny Hill theme music.

All part of the hobby. There is a certain satisfaction in being able to solve all the problems. But no doubt, sometimes some mighty fine bouts of high frustration too! 😁

Well...never thought I'd be busy with computers outside of work given the weather......I did replace the shocks in my 93' Explorer last weekend, this week+weekend though....so Auto season has started....

Latest events?

- Bought a DFI MediaBook (NanTan 9200M) for $55 on evil-bay, bought a $15.00 charager for it as well. Currently plotting to put an Active Matrix panel in there once I figure out the pinout from the graphics chipset to STN/DTSN adapter board. Put the FreeDOS drive from my M/75 in it - though toying with reloading with DOS 7 and Windows 3.1. - as then I can run Ultima 7 and some other games on it that don't run on freeDOS properly.

- Spent Wednesday morning tuning/tweaking, fixing up the Versa P/75. now the battery latch works again and it feels a little more solid. I need to figure out a good way to fix the screw anchors on the bottom though -and my M/75 is getting close to needing the same treatment.

- Brought the M/75 in last night and did tuning/tweaking to Windows 95, tried installing Exult (failed), tinkered some more with WSS (I seem to be getting better at that), downloaded a few WSS compatible games (William Shatner's TekWars, Flying Tigers I & 2, Get Losts, Giana Sisters, Abuse, and FitUp!), and did some dabbling with OHRRPGCE on it (been building a sci-fi RPG of sorts on there - which I'll probably never finish TBH - like every other game I started developing).

- Tonight I inspired a mass firesale of my big-box DOS games on e-bay with people offering to me left and right just before leaving for work. Never thought a bunch of old Sierra games would inspire such madness. Now I'm wondering why I did not do this sooner! I'm also planning to put 2 systems on the block (GEM 286 and my NEC Ready 9522).

After Asking a Coworker for a Laserdisc player, which he was more than glad to let me have thanks to his five spares, I decided to expand my collection of old Media. Of course, none of it was Laserdisc today because I didn't find something that just stood out to me. That said, I did pick up Ben-Hur on Betamax (because that exact phrase is fun to say) and The Menagerie on CED. I'll never have a reason to play my CEDs, and am explicitly never going to pay for a Betamax player, but they're interesting to have as part of a dead medium collection.

It's unfortunate that laserdiscs are to be counted as a medium that can suffer from physical rot. I think it's a result of the discs being manufactured as two separate plates and it's the glue in between that's decomposing.

Luckily, a lot seem to still be holding up well.

I honestly can't understand how disc rot happens, I should research into that somehow.

Not sure about laserdiscs, but prolonged exposure to sunlight and heat can most certainly cause CDs and DVDs to become unreadable.

I've personally had several game discs go bad due to this.

Sometimes its the glue they use to bind the layers of the disc together, all it takes if for a tiny part of it to decay and itll spread to the rest of the disc spindle, I have had this happen recently, destroyed a lot of discs. The other is the binding simply gets to old and when the drive spins the disc up it tears parts of the recording section off the disc surface.

Oh noes, the cap let the shmooo out 😁

Fixed some bent pins on a motherboard I bought "as-is" for a discount. I knew that the damaged area had very few components and saved myself some money. The pins bent back easily and the board is fine with no visible damage to traces or components.

The quest is finally coming closer to an end.

Boards left to check:
3x LGA775
2x Socket A
1x Socket 7
1x Slot 1

Planing to get done with LGA775 today and continue with Socket A tomorrow.
So far 3 boards that aren't working at all and 5 with partial malfuctions.
