| 669312 | 2008-05-14 10:02:00 | Is that actually possible? I mean, you can quit back to DOS but as far as I know there is no reboot button. | Agent_24 (57) | ||
| 669313 | 2008-05-14 10:12:00 | !!!!....LOL, I cant remember.....I'm sure we did on Novell network....what version ?, workgroup? | SolMiester (139) | ||
| 669314 | 2008-05-14 10:18:00 | Wait a minute, i'm thinking of nt 3.51!!... | SolMiester (139) | ||
| 669315 | 2008-05-14 13:32:00 | Wait a minute, i'm thinking of nt 3.51!!... That explains it :lol: Well, I got a new BIOS chip (old one was EPROM) and put the latest BIOS on it - but it just does the same thing :crying I think I'll go to sleep :badpc: |

| 669316 | 2008-05-15 00:16:00 | actually i do have a few 486's myself, an (w)intel 486 toshiba (windows 95) and a cyrix 486 desktop triple booting 3.11, NT4.0 and 98 :nerd: . (hens teeth anyone), but to be honest i wouldnt have a clue why the mobo is hanging on "warm" reboot. can you get into bios, do a default settings restore (remove the bios battery if it has one instead of a RTC chip with one on it). if you can use a DOS boot disk with killcmos on it to reset the bios/cmos to null values and reset the settings but although i do doubt whether it is bios. i assume everything on that motherboard is actually functional etc including ram and HDD. | williamF (115) | ||

I've tried clearing the BIOS settings, I also told uniflash to clear all CMOS settings when I flashed the new chip (with a BIOS version 4 years newer than what I had), I doubt it's the BIOS either . I'm using this board because it was the only working socket 3 I had that didn't have one of those stupid dallas RTC+battery boxes soldered to the board . The battery is a normal button type and while it is also soldered to the board, it will be much easier/cheaper to replace (actually I'd replace it with a cr2032 holder) I'm pretty sure everything works on it . I took out all the unnessecary cards, swapped video card, CPU and IDE controller and still had the problem . I think the RAM is fine, guess I should probably test it and make sure . . . |

| 669318 | 2008-05-15 00:45:00 | okies, you may have to live with powering off and turning on to reboot unless the CPU is at fault, although was the CPU working in the old mobo when it was working? it might not be clearing the CPU when the cpu's reset line is tripped. are you using the CPU from the old mobo or the one with that mobo you have | williamF (115) | ||

I could try the old one I guess |

| 669320 | 2008-05-15 02:33:00 | So I put my old 33mhz CPU in but it started running at 40mhz and caused random reboots and freezes So I rechecked the jumper settings after getting a scan of the original manual from mobokive and found this: www.imagef1.net.nz Someone had set the jumpers to the highlighted settings (which doesn't make sense because it's using half from intel and half from cyrix and must be an invalid combination) So once I changed JCX1 to open instead of short and I tried it again. It worked fine. Then I put the DX2 back in and that also worked fine. :D now I can reboot without freezing! :punk |

| 669321 | 2008-05-15 09:55:00 | congratulations. :thumbs: it must have been used on a cyrix based 486 CPU in its previous life:D | williamF (115) | ||
