I wonder if the corruption is there all the way through 98SE setup.. Because, the first part of setup is based on a cut-down Windows 3.1 (mini.cab) with a vga driver (if setup was started from DOS). Second part is Windows 9x then. You'll notice the transition by looking at the dialog windows. …

I think the same. Also, maybe that SCSi isn't properly terminated at some point (better check).

Who was it who said that you could run a power station using a ZX81? The ZX81 was a black and white, silent British 8 bit computer, that came with 1KB of RAM, though you could increase it to 16KB, and maybe more. I don't know, but you remember me of an old article (p.26) about measurement & control …

I guess you were lucky that it was a permanent magnet. If the floppy was exposed to something pulsing (CRT, m. loop antenna etc), the effect may have been worse.

That's right. With 256KiB, 640x400 is about the maximum resolution (in 256c). Unfortunately, this mode isn't supported by Windows 95. Some DOS games with VESA supported it, though (Höhlenwelt Saga ?) . If memory serves, some vendor drivers for Windows 2.x and Windows 3.x exited once. (Paradise …

Yes, you can do that. Back in the day, this was common practice, even. If an old CMOS Setup only had hard-coded settings for fixed-disks, choosing a small drive from the list which was within the specs of the HDD was okay. Nowadays choosing a setting that does not exceed total capacity also works ( …

Hmm. I can't give a specific answer, but.. Our 5,25" and 3.5" floppies from the mid-80s and early 90s are still readable. We stored them in diskette boxes in a cabinet originally (some from the cp/m era were continuously boxed-up in the attic since the move), now these are on the loft/attic in solid …

Same here. Never got it to work in 640x480@256. It had got a mode utility, though, to switch to CGA, EGA and Hercules emulation modes (works). Plus, it supports 800x600@16 - according to the chip's datasheet. - Again, never got that to work, either.

Hm. My experience was a bit different here. Back in the 90s, I had barely issues with 5.25" 1.2MB drives in comparison to 3.5" 1.44MB drives. (In these times, my father and me often got ourselves 5.25" shareware floppies! ^^) Perhaps the problems are with the disks really. I remember that when I got …

Makes sense. Does the mainboard (486, 586 ?) support LBA already ? I grew up with older Pcs and remember that some supported E-CHS aka LARGE, which also had an ~8GB limit. Anyway, just saying. It's unlikely, but maybe -if the CMOS Setup is set to AUTO- it could be the case that the HDD detection of …

It's also because of the use of interrupts. Some ports use more of them than others (USB vs. PS/2 vs. V.24). Especially in old pre-586 systems, old serial UARTs were the culprit. Gratefuly, they can be replaced. See https://www.tldp.org/HOWTO/Serial-HOWTO-18.html , http://www.byterunner.com/why.html …

Hi, as far as I remember, in DOS, hard disks (or more precisely int13h BIOS devices) have priority over CD-ROM and network drives. You could try to specify drive "E:" for the CD-ROM drive in DOS. Not sure how muich this would cause compatibility issues with DOS games, though. Windows games were more …

Hm, As fars as I recall, you could try some dynamic drive overly software (DDO) for Windows 9x. This could work around the BIOS limitations. However, care has to be taken here. It could be the case that Win9x uses a different drive geometry than Windows 2000 then. By the way, that also caused some …

So you're using the original Gotek firmware still ? If yes, you can try creating you own floppy images using WinÍmage. Open it, klick on "new" and drag your games files into it and save. After this, you can write them to the Gotek. But beware, the original Gotek software is very restrictive in …
