Not entirely sure what you mean by jumpers or what they do but i know i have the JP in this picture (should be near top middle).
Yes, JP1 is a jumper block.

There are 4 positions, as described in the 'Board Configuration' section of [here]. 'Open' means that no jumper is fitted; 'closed' means that a jumper is fitted. The blue things are jumpers. So, your card, as expected, is configured for the defaults, which includes the card (card, not XUB) being configured for a base I/O port address of 300h. So, we can rule out a missing jumper on position 2 as the reason why your XT-CF-lite rev.2 card is not 'seeing' the CF card.

I removed the mouse card and i'm getting the same error, ...
Forget about the "Error 1h" for now. There is a problem happening before that: your XT-CF-lite rev.2 card is not 'seeing' the CF card. When that happens, the XUB will display the make-model of the CF card to the right of "Master at 300h:", as shown at [here]. We need to get that working.

Try a minimum configuration of only the following three cards:
- IBM Color/Graphics Monitor Adapter
- IBM 5.25" Diskette Drive Adapter
- Lo-tech XT-CF-lite rev.2

And note that slot #8 is special. Only certain cards can be fitted to it. See [here].

... could be that the cf card is modern but i figured it wouldn't be an issue since i have it formatted and partitioned
Do you have any other CF cards that you can try?
For the make-model of the CF card to get displayed by the XUB, the CF does not need to be partitioned/formatted.

I currently only have 1 CF card (which was purchased for this purpose). Removing the cards didn't change anything

Is that a 64GB CF card i see in post #19 ?. You should try a smaller CF card, 4GB or less, The recommended way is to set up, FDISK / FORMAT the CF card on the computer it is intended for, Using another computer can lead to problems.

it is a 64gb cf card, i'm willing to buy/try another cf card might just take a while for shipping. When it comes to formatting the cf card on the computer it's intended for i'm not sure how possible that is since i don't have a DOS floppy.

when buying a cf card do i have to look for anything specific? Don't want to buy another card that ends up not being recognized

I've had some experience with a handful of CF cards that were used for years with a Nikon DSLR, some cheapos that I bought on eBay, and some I bought new retail. Based on what I've seen so far, I am now sticking to name brand 2GB cards. I gather that older (and smaller) cards weren't really built for what we're trying to do with them. Newer and larger cards over 2GB in size are bigger than DOS can use fully without using multiple partitions. And that sometimes adds to the confusion. Even then, sometimes I get a dud. But the duds so far have still usually worked in the DSLR. They just won't cooperate as a DOS "boot disk".

Plus, if you get a dud 2GB card for $10 or so, you won't be quite as sad as getting a dud 64GB for four times that or more.

I have seen recommendations to look for cards that specify UDMA, but I've had duds that said they were and had others that didn't mention it work fine.
