Hi,
The password that i found only and used to access the bios was lambkeoghs it worked and since i unlocked it, it has been working ever since, one thing i wonder how does this machine keep track of bios settings, there is no cr2032 and when the power cord its connected its keeps settings, i suspect the blue cap. I also remember reading in the post where i found the password something about it being universal, anyway hope it works. regards.

In the TC100 the cmos battery is inside the Dallas clock chip. When I first got the PC I had to replace it to get the system to work at all.

Hi ,
I dont see one on my, i mean is it the thingy next to network port in your picture?, In my unit i think that is a relay that old network cards use and i dont think it is removable.

That's a filter for the Davicom ethernet chip, yes. At the very least on my TC-II, there is no discrete RTC or battery. The ALi M1487/M1489 chipset combo has a built-in RTC that I think these things are set up to use, but if there's some sort of rechargeable power source integrated in it, mine is totally dead. I've got mine set to retrieve the time from the network on boot, and that's about as well as I've managed to do so far.

Sorry to revive an inactive thread, but wanted to put this here in case anyone was looking to learn more about these Boundless TC systems. I did a video recently on turning my TC325 into a DOS gaming rig:

https://youtu.be/rEsNgvNyFKw

There is information there about the hardware components, how the UNSILENT application works as well as how to do an RTC battery mod (which I haven't done yet).

Since doing the video, I have had some success getting an Award BIOS for the ALi M1486/M1489 chipset working on my system. It half works, but the systems hangs for a long time on boot and I haven't been able to get the serial/parallel ports to work. The Cirrus Logic VGA BIOS shares the same PLCC32 chip with the Phoenix PICO BIOS, so I have to use an external VGA card until I can figure out how to combine the two BIOSs properly again. Still lots of testing to do.

Hi! I saw your video 😀 great work. My machine is in storage for now, your video revived my expectetions of giving it another try some day. 😀 From what i recall i messed with it so much that stupidly deleted the onboard 4Mb flash partition scheme with fdisk , and cant recover it. Fdisk only sees kb's of disk size. Also tried some tools used to partition and format msystem's docs but these seem to be just for msystem's docs. they dont see the 4mb flash on the board. Anyway the machine works without the 4mb flash. it would be great if you could hack an unlocked bios. Best regards.

If you just deleted your partition with FDISK there is hope.
I hope you haven't written a new partition with new data ...

Hi,
I think in the process i created and formated a new partition yes, showing only its total size of a few bytes if i recall. I will try to post screenshot when i have the oportunity. Thanks.

Very interesting video and fun to see this thread pop up in it. Seems the boundless machines didn't vary that much in design, as yours looks a lot like my TC-100.

Keep me posted if you find a permanent solution for the BIOS. Would be very interested to use that 😀

Hello, Sorry for resurrecting the old post. Just got a TC200. Im having issues booting from a CF card. I have added C:\UNSILENT.COM the the autoexe.bat file. I just get a blinking curser. Thanks

Hi, i have not messed with this machine in quite a while, i intend to get back to it 😀, others made it seem right trough, and it probably is 😀 but i remeber, i think and dont know why, but when i kept pressing F1 during boot, it seems to do something, otherwise i got the blinking cursor. try pressing F1 several times during boot to what helps. Any others have made some proper work on this machine. I recomend you wath this video https://www.youtube.com/watch?v=rEsNgvNyFKw&a … nel=vswitchzero from vswicthzero. 😀

Hmmm makes me wonder if it's possible to sneak out floppy/IDE/Power cables from the back. Those could then be connected to external drives on demand. Would look ok if the drives have an enclosure too.

There is an internal power connector with the required voltages, i guess you can do that if you want 😀

So i was playing with it last night and seen where you guys uploaded archives of the internal drive. I was able to hook up a floppy with the unsilent.com and install 6.22 on the CF. I wouldn't of been able to with out it. So thanks for that. My current only issue is my system didnt ship with any riser for isa slot.

Mine also didn't. The original isa riser is bit more complete with some capacitors and dom or doc in the back if i recall from vswitchzero video, but you can purchase one that fits. i got my unit a few years ago now and at the time i order some from mouser. probably the high will not fit exactly but it will do.

You wouldnt still have the part # would you?

i think it might had some inscription? i will post a picture.

i will post a picture of it dont worry 😀

Here are some pictures of the ones i got. As i said its not a perfect fit, but it can be fitted. I've not messed with this machine latelly, has a matter of fact i think never got put the cover with a card in 😀 it has always been kind of the dargging project all the time 😀, anyway i am sure thats an easy problem to solve, however it might be better alternatives.

Hey, not bad. Looks good to me! 😃👍
The card itself fits perfectly fine, it's just the slot bracket that doesn't fit.
Technically, you can remove it and use a piece of plastic instead (that way, you can make use of the two mounting holes).
Say, from an old VHS enclosure (since it's flexible).

It can be a bad one from the 90s or 2000s, since VHS are becoming retro, too.
The big old 80s VHS enclosures use more fragile plastic, anyway, and are well padded on the inside (tricky to cut out).

In either case, the old bracket can then be used as a template. 🙂

Great to see you managed to find a fitting riser. Mine has an ISA riser, but I could use a PCI riser too to add some more cards.

i think the pci has more options i recently saw some on ebay and think i saved it. there were both directions. there are also cables as a last resource 😀
