Looks like bad options selected in BIOS. In case you have a CF as a HDD, have you selected the correct options? Is it connected to power? Sometimes those cards start but can turn unreadable if no power is connected (usually a floppy connector).

Tried again to repair the Ram 2nd channels (A2/B2) on a 775 DDR3 board. Suspicious traces were fine, voltages are right. The only reason it won't read those two slots is because the NB isn't getting some signals or the NB can't communicate correctly with the cpu. Something is busted for sure.

Well, I'll say so far with the iMac it's pretty nice now that I got the triple boot working. Had to check the budget this morning for a new key for Windows 10 for it though (been using the same Win7 key since 2014 when it was RTM at Microsoft - where I worked). 22H2 does not like that key, lol. Now …

Decided to get ready to thin my modern herd a little bit today. Decided to keep the Late 2015 21.5" iMac and set it up to triple boot OSX Monterey, Win10, and Linux Mint. Been a bit of a learning experience and quite an adventure thus far. Got mint and OSX to dual boot, Windows without Bootcamp …

OK. No problem. I also plan to put a modded BIOS by me on that A7N8X-X when I Have time. That ModBIOS 1010 consists of unlocking hidden options like Small Logo (EPA) Show and some overclock options, and also FLoppy DIsk B setting. Should I flash the ModBIOS 1010 made by me on that A7N8X-X? If you …

Found the component that was causing a short on my GTX660 12V 6-pin connector line. A VRM was dead, shorting to ground. Source was shorting with ground and resistance instead of 40K ohms, was like 20 ohms. Could single out the dead vrm and desolder it. Thanks to multiple layers and no lead solder …

Did all tests of the Phil pack. With the 5x86-120 (3x @40mhz) the J2 BIOS is less stable with results. I prefer the X version over this one. I'm going to keep the latter, but honestly it's about personal taste, in games it'll do as good as X. Statistically the difference isn't high enough, it's …

Ok, it wad broken traces. I feel like an idiot. 😀 But it was a straight cut, razor like, probably clashed against another sharp pin in the box it was stored. Took me 10 times and light at angle to spot it. It was in fact connecting BUS to MC74F245N

All ISA slots works with 16bit cards. VLB slots work with VLB controllers 100% To me it's a matter of signal not being processed correctly by the GD5428, 74F32PC (close to crystal) or MC74F245N (block of 4 close to sockets). Can't guess anything else. https://pdf1.alldatasheet.com/datasheet-pdf/view …

Crystal was replaced but no change, still out of range. This is what happens: 1) display bios info // out of range 2) blaks out in transition to mobo post info // goes black 3) bios post // out of range Basically when it should output a signal the signal is not a valid input for the screen.

so again, does that: >>Bios is working, I swapped it with another ISA card (CL-GD5420-750C-C) and it gives the same error, but on the ISA it displays everything fine. On the VLB still "out of range". mean CL-GD5420-750C-C works fine in short only ISA slots, but fails when plugged into combined ISA/ …

so the ISA card plugged in to ISA slot with VLB glued to its ass is also doing weird things? sure sounds like that ISA slot went bad I don't understand this. No, I didn't "glue it to its ass". :) I took the bios chip from a GD5422, tried on VLB: same. Tried VLB card Bios on ISA card: works as …

On the card, what actually generated the signal? The GPU or another chip? The GPU generates the pixel clock, the horizontal sync signal and the vertical sync signal. Every timing is derived from the 14.318 MHz crystal on the graphics board. I'll replace the crystal to see if had anything to do.

This is the ram. 80ns. Could it be a ram issue? I would be a fool to say "surely no" without careful testing, but getting the correct frequency from a Cirrus Logic chip doesn't require working RAM at all. Thus I conclude there has to be something different wrong with your card if your monitor …
