Re: Installing OS/2 Warp 4 From Hard Drive

It is simple to create the CD-ROM version installation floppies. For Warp 3 at least. I think it is the same for Warp 4. The floppy disk images are on the OS/2 installation CD-ROM in a folder named [\images] and you can use the command savedskf.exe to write the image to real floppies. Work on MS-DOS …

Hi, Remembering from the old time with OS/2 Warp 3 on a PS/1 with a TEAC CD-55A CD-ROM drive using a Mitsumi interface if I'm correct. The CD-ROM drive needed a driver for it to work in Windows NT 4.0 and OS/2. For OS/2 I made a copy of the install floppies and added the needed driver taken from a …

Yes indeed. That too, the fuse is in serial right next to it. Thanks for the precision :) With hardly any feedback from here I decided to order the components and give it a try. I received the components today and made the repair. Tested the electronics many time on many steps. I got a little …

Re: 2x floppy drives in Windows 95: Both access same drive???

Yes, it's probably a registry issue from a bad configuration that occurred somewhere. DOS is using BIOS calls & interrupts with the CPU in real mode to command the floppy controller. The Windows 9x uses their own way to talk to peripherals. Through different software layers from the user interaction …

Hi. I suppose both FDD are on the same cable. Did your cable look like this one (with the twisted part on the ribbon, in red)? It should and the wiring should be done as I indicated. Filename FDD_cable.jpg File size 103.12 KiB Views 630 views

Hi there. The PSU of a Pentium III PC pop after turning it on. The PSU was made in 2003. As soon as I heard the noise I cut off the current. Then I opened and dismounted it to check the inside. What I have discovered, on the high voltage side: a crackled thermistor an odd looking filtering capacitor …

Which is better? ... in what field? Better in the void mean nothing. What do you want to do with it? For what I know about this chips, they are both based on the same design, both are good for 2D (DOS & Windows) and both are pitiful for 3D but the ViRGE was sold for it (Edit: meaning it has S3D and …

Hi. SB16 emulator is not supported on Windows NT to my knowledge. Use Windows 98/98SE/ME with Windows 9x drivers. Then it should work in Windows and DOS mode. But if you have a problem in DOS real mode, read this thread: https://www.vogons.org/viewtopic.php?t=55047 to have clues. If you are running …

Hi. My big recommendation: find a qualified person to do the job. If you are asking how to replace a chip, it means you have no skill to do it. So by trying to do it yourself, you will most certainly get what you want not. But to answer, the "best" way I found to do such a thing, is to unsolder a …

Unfortunately tantalum caps on 12V rail are prone to fail. Sometime they can explode, sometime they just have a very small burnt dot that make them difficult to identify. That's very very common. My assumption is they put capacitors in parallel to increase capacitance while keeping the cost low by …

Anyway, I would stay on MS-DOS 5.0/6.x for a 486 DOS PC. Why would you use MS-DOS 7.x? For the long file name support? The only practical reason is FAT32 partition support for MS-DOS 7.1 unless the OP wants to run Windows 3.x (and certain low level disk utilities) without any compromises and/or …

MS-DOS 7.1 is a custom mod extracted from Windows 98. But as Windows 98 can run on 486 DX2, it should work. I don't see where the issue can be located here :/ Anyway, I would stay on MS-DOS 5.0/6.x for a 486 DOS PC. Why would you use MS-DOS 7.x? For the long file name support? Maybe FreeDOS would be …

And if you are running DOS 7.1 in safe mode with nothing except the command prompt? Edit: Accessed by F8 when Starting MS-DOS... is displayed. Then No for everything.
