I think its the idea which is daunting, once I start probably not so bad! I have to also dismantle the earlier PC a bit to extricate the other PSU! it does sound like I have no choice but to exchange PSUs, is there any chance the problem is with the mobo? or would the PSU catch any problem before it reaches the mobo? ok, will do this as the next experiment, before trying to change PSUs. if it is just the hub which is malfunctioning, that would be better! will try that as the 2nd experiment, as asked above, could the power outage have caused a problem at the mobo? eg where say hub and PSU are fine, but not the mobo? with other things they cover "acts of god", eg storm damage to a roof, but they dont cover wear and tear. accidental damage has to be opted into. I think the power outage is an "act of god"! my current policy covers damage up to something like £2000 per item, anything above £2000 has to be individually listed and an extra premium is charged for those. but the UPS presumably supplies the 50Hz 230V voltage? they must then convert the battery DC to the 50Hz 230V? is the battery just a normal rechargeable battery, something like lithium ion? my laptop has a battery I cannot remove, if I switch off the mains it just continues with the integral battery, so in a power cut I think it will just continue, but a surge maybe could cause a problem to its transformer? what I meant was when the UPS replaces the mains, I would be asleep so wouldnt be able to cleanly shut down whatever I was doing. how long does the UPS power the PC for? but maybe a higher end one does! its like you can buy plug adaptors which shield the user and equipment, but the modern fuseboxes in the UK shield at the fusebox ("consumer unit"), eg with a hedge trimmer by accident I cut the power cable with the hedge trimmer, and there was a brief orange flame and a sound. The consumer unit switch had tripped, I flicked that back. I had cut the extender cable not the integral cable, and when I connected the integral cable to the mains, no problem! the consumer unit shields both the person and the equipment, I just wonder if it would shield the computer's PSU? I have uploaded a photo of the consumer unit: consumer unit I think the multiplugs with the PC etc are from items 3 or 11, when they install that, they have to test all circuits and forward the certification document to some governmental authority, probably local government. And to give the customer a copy of the certification. when the guy did the testing, he located a missing circuit, which we eventually found which was a nonstandard arrangement. very interesting image! I was dabbling with 2 specific early phases of that for 32 bit PCs, where I would boot code directly from a floppy, which would be the stage one boot loader in that diagram and none of the steps beyond that, and I wasnt aware of the steps before that! where I was just at steps 7 and 8, if you answer no to the first question step. I wasnt aware of the other steps of the diagram, I would generate the floppy from a Windows command prompt using 16 bit BIOS code, to load the code to the floppy. then reboot from the floppy disk. I think the 32 bit windows command prompt has an emulation of the BIOS. my guess is I could put that kind of code on the first sector of a CDR in this era, and boot from that? or the first sector of a hard disk dedicated to the experiment. the code on the first sector of the floppy then via the BIOS would load further code from the floppy and execute that. my code written for an old era floppy disk, would work from a USB floppy also, where the BIOS emulates an old era floppy from the USB one. ie no USB commands needed. do you have any links to the programming environment for todays 64 bit PCs for stage one? have they replaced the old BIOS with some new kind of BIOS? maybe a 64 bit BIOS? eg the mobo early startup has a mouse pointer and graphics imagery, that isnt possible with 16 bit! as there isnt enough memory for one proper video screen, instead they used tricks, where 1 byte will encode a font character on the screen. 1 HD screen is some 2 million pixels, not viable from say a 32kilobyte 16 bit machine! with the 32 bit PCs, you have a 16 bit environment much like the PC was in 1980, where I used info from a bygone era, the code then if it wants can promote the CPU to 32 bit, using supervisor level commands, and then with the 32 bit code use supervisor level commands to promote to 64 bit. But I think they have changed this for todays PCs, as you cannot install 32 bit windows. so maybe stage one is immediately a 64 bit environment? https://laymentogeeks.wordpress.com/wp-c...8/rurr.jpg is there any way to pause that slide show? as it rushes to successive slides before I have completed reading any! if I read it at that speed, I wouldnt have time to understand what I have read!
