When it does enter the floppy/hdd boot process, that connection is there. Based on the symptoms you describe: * not enough power goes to the bootdevice, power it externally if possible. * a broken wire or trace Yes, that was my first thought about lack of power, but then I tested old HDD in BIOS …

So I am assuming you acquired these: drivers: https://thinkpads.com/support/Thinkpad-Drivers/download.lenovo.com/lenovo/content/ddfm/765d.html manual: https://thinkpads.com/support/hmm/hmm_pdf/vol4hmm.pdf Page 444: I9990305: No bootable device. Yes, not the driver part yet, since it's not booting. …

Yeah, vinegar make wonders, same copper foil after some soaking and zero rubbing

Disassemble the whole laptop and check if the standby battery has leaked onto the motherboard. Check for dried out caps in the power area of the motherboard. Sometimes leaving the system on the charger for a day does do wonders too. Thank you for your advice, I already disassembled the main board( …

Ok, so while I have no options to boot, I ordered CF to laptop IDE 2.5 adapter, and PCMCIA to CF card too. Hope these will work on such an old machine, they are very cheap anyway.

Thanks, so I opened floppy drive, and looking pretty good and clean inside. Did a simple head cleaning and sightly oiled screw shaft, still not booting. Guess I should try to clean/reset a motherboard next

So I got this IBM Thinkpad 765d in a pretty good condition overall. Only thing was slightly bothering me is a barely noticeable "moss" smell, like it was stored in damp environment. Got it without AC adapter, so I connected my spare Lenovo 90w 20V to 2 pins and it's working fine. Even original Li- …

Found a pretty new and detailed guide about this: https://gekk.info/articles/ata-dialup.html

For the last 10 years or so I was considering modems as useless piece of junk. But now it's vintage enough for a closer look. So, I found a couple of ISA Sportsters, external Zyxel and even some late PCI model. What's the easiest way to use them, since I have no landline for years? I'm thinking …

The biggest weakness of the NuXT right now, as I see it, is the trident graphics. While it is a great 8 bit SVGA card, there is a fair number of titles that just won't run properly on it. They need an actual CGA card , sometimes with composite output, in order to work correctly. I can understand …

Tried to download zip file, but seems like Phil's site is down? Would be nice to have at least couple of mirrors for that. In the meantime found old(?) version on archive.org: https://web.archive.org/web/20170121115809/https://www.philscomputerlab.com/uploads/3/7/2/3/37231621/dosbench_v_1.4_jan_2017 …

Ok, so a quick update, card was definitely fine, problem was the adapter. I bought another one, with a bracket and it's working fine with any cards I have. So, lesson learned, do not use a cheapest option.

When I first heard about CF to IDE adapters, I thought it's 100% compatible with every card, since Compact Flash is basically compact IDE, also every card should(?) work with voltages from 3.3 to 5V. Only complicated part is an old hardware, BIOS limits etc, but any card itself should work? So, I …

I'm getting strange results from PIII-600 Katmai, I can disable L2 cache in BIOS (no L1 option), Topbench drops from 453 to 69, and that's ok. But with SetMul disabling L2 via L2D I see no effect in speed. And after disabling L1 with L2 "enabled" I'm getting same 69 result. So, L1E L2E = 453, L1E …
