No problem, you're welcome. 😀 I'd go with Fast PIO 3 first. The other one may use single-word/multi-word DMA, which was used before Ultra DMA (UDMA). - And if the CF reader is not fully wired (some have no DMA lines), problems could occur.

To my astonishment, when I created a second partition on the drive with MiniTool, Windows 10 could see it! I'm curious - does Win10 think it's a removable media or a hard disk ? Went into the BIOS and changed the IDE setting of the hard drive from 'Auto' to 'User' and enabled 'LBA Mode Control': …

I had a ~14" IBM fixed-frequency monitor all the way though the 90s. My dad had a 20" CRT monitor since ~'92, though. It was no VGA monitor at all, since it had BNC connectors for each RGBHV signal. ^^

Thanks for the feedback, people. I'm not sure which version I tried, but at least chkdsk /f didn't show any corruption on that 30 years young 20MB drive. ;) Which one would you recommend ? And should I run the CGA Compatibility Tester ? If so, which ones of these tests could give us a clue ? Edit: …

Alas, it didn't work. Disabling the FDC portion on the ISA card had no effect. I did thsi, because I …

Hello everyone, You may have already seen my other thread , where I had slight issues with my 8088 PC. As already mentioned there, the 8088 MPH demo isn't working on this very same computer.

Yup, I'm also a bit surpsried. I wonder if the BIOS is configured to force LBA mode or if it is still set to "AUTO".. Since the Compact Flash card is an ~8GB model, it might be still within the realms of the old L-CHS/P-CHS translation model. http://web.allensmith.net/Storage/HDDlimit/Address.htm# …

It's just a wild guess, but maybe both BIOSes differ in the total amount of usable cylinders they do report via the old function calls. This could result in some kind of garbled data, as only one PC sees the "other half" of the card. The Windows NT machine is likely not bound to the usual DOS or …

Thank you both of you! So it's among one of the things I had feared. Changing the BIOS to a generic one could work, but it would also take away a bit of the personality of the machine. Also, I'm not entirely sure if the machine is a faithful IBM clone. :confused: The page of the other user at the …

I've got an old 286 (w/ onboard FDC) that refuses to work with multi-i/o cards with built-in IDE+FDC controllers. Disabling the FDC portion via jumper has no effect. The internal floppy controller would nolonger function, as long as such cards are installed. If I remove them, the system instantly …

Um, I don't mean to be ignorant or rude or something like that, but what's the matter with flash memory (why no EPROM) ? A few notable exceptions aside, I've rarely had serious trouble with classic UV-EPROMs so far. 😕

Ooh sad ! I'll try with 7 then. Most programs works on it so it's fine :) From my understanding, Win10 is lighter on system resources than Win7 is, even if 10 requires various newer CPU features. This probably won't end well... Windows 10 is in no way lighter on system resources. It is the only OS …

Thanks everyone for the replies so far! :) Here's a quick update: My father got hold of an an old NEC V20, ceramic type ( D70108D-8 ). It's an 8MHz version, CMOS, the type of V20 that was also used in Turbo XTs. Apart from this, it looks identical to the NEC 8088 that was in the machine originally. …

The SX may have been a lousy chip, but some 386SX machines were also combined with late, powerful 286 chipsets. These had got advanced features, like options for wait-states, EMS, shadow memory, interleaving, etc.
