If you need the drivers for this model, here they are:

Thanks for that! But I am not sure if a card for comparision is sufficient as the parts are not labelled and we cannot figure out what kind of cap or resistor is missing?

Sometimes the parts are labelled.
I'll take a look tonight (I'll also take pictures) and report back

Sure, it works, but it's not the same as being able to boot from a 1.44mb floppy.

I lost track about it, but I believe some user successfully combined
FDC BIOS and XT-IDE Universal BIOS into one single ROM image.
I think the thread was somewhere at vcfed.org.

Yes, I am also wondering this has not been done before? It should not be a big deal to put 2M-XBIOS into an option-ROM.

If not and some people are interested I can do this.

Other possibility would be to use the floppy controller on a SCSI-Adapter like the Adaptec AHA-1542B? Just tested with a AHA-1540CFS. The BIOS works and I can enter the SCSISelect, but my Adapter doesnt have a Floppy interface.

carlostex used to sell his XTIDE CF ISA cards with an option about integrating the HD FDD bios as well, I think he has a thread here somewhere about his XT build that incorporates all the above

Congrats on getting an XT up and running. I've always liked the XT era PCs for nostalgia alone, as my first proper PC was an 8088 (a Siemens 10MHz CPU).

Was going to build an XT system myself recently, but I hit a stumbling block with regards to lack of an XT keyboard. I knew I had one, but it has since vanished from where I thought it was stored, so I'm leaving that project on the backburner for the time being.

Yesterday I was in my storage room and inspected 4 old Cherry AT-Keyboards: 3 of them had the XT/AT switch on the back. You usually dont need a special XT keyboard.

Regarding the floppy discussion I found this in the PCXTBIOS3.0 Package
http://www.phatcode.net/downloads.php?id=101

The Multi-Floppy Floppy BIOS Extension provides support for up to 8 floppy
drives connected to two floppy disk controllers (FDCs). It supports any
combination of standard IBM PC/XT/AT and PS/2 floppy drives, with disk sizes
from 180 KB to 2.88 MB.

So this should do the job...

I've uploaded two close up pictures of the missing components on your card.
Unfortunately, there are no markings on the smd capacitor but, someone here with more experience in this field can probably take an educated guess as to what the specifications of that capacitor will be.
The other one is a voltage regulator (79L05).

Thanks Jesolo! The other missing part is labled "FB13". This does not seem to be a capacitor but a Ferrite bead? Maybe I can desolder a one that looks the same like FB12. But dont know how to figure out the characteristics, have to google. And my multimeter can only measure resistance...

Will see 😀

yes that's ferrite allright, you can just replace with a solder bridge for testing and see if that fixes the issues

Hmm I bridged it but it doesnt change anything.

I also dont think that this voltage regulator is relevant for FM playback only. And I dont see any other damage on the card.

After beeing slow i just noticed now that i need a EEPROM for my nic since it isnt really standard on nic cards but the dip socket exist, just that it is emty hehe

Now lets see how long it takes until it arrives so i can try my nic cards 😀

Indeed 😉 And dont forget the programmer...you cant program it in the ISA-NIC.

If you have a spare mainboard you can also take its eeprom and hot-flash it in another board as interim solution 😉

Lol and I tough this would be easy :p well I only have 24 pin sockets for eeprom on my cards so I will try that first.
Problebly need a programmer now , thanks? :p it doesn’t hurt to have one any way 😀

That's why I have PCI NICs and Flashrom.

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. 😕

Dont know, because you need an additional UV Eraser?

Yes, I also started with this. But now I am so happy I invested 40€ for my TL866CS. No more issues with incompabilities and its much easier to handle the chips in the TL compared to a NIC or a Mainboard. Not to forget the included Soaftware which makes it very easy to handle and edit the images.
