Early versions of DOS assign drive letters to all floppy drives first, then the hard drive.Well, this got stranger....now it booted and shows drive E instead of C like it used to.
So I would need another PC and put the .bin file you sent on a floppy, then boot from that and it would allow me to flash the correct bios to the eprom I screwed up? I dont have another PC to do that with.

Have you recently done anything related to floppy drives (e.g. changed floppy drive count switches on motherboard, added floppy related driver software, added a floppy controller that has a BIOS ROM) ?
It makes sense to me that what you did was opposite - the switches were set for 1 drive and you changed them to 4 drives (A: B: C: D: in early versions of DOS).Yes. I did switch the MB floppy switches as I noticed they were set for 4 floppy drives. I set it for 1 floppy.

On the switches, are you confusing ON with OFF - see [here].
Provide a good photo of both sides of the VTech card. That may help us work out the card's purpose.One board is an IBM that is jumped to a VTech board, then to the floppy drive.
Using only the IBM floppy controller, and cabled and jumpered per [here] :I also tried using each floppy controller board independently without success.
I cannot see '2 beeps' at [here]. Are you able to provide an audio recording?As a side to this response, the PC boots very randomly, sometimes no memory count.
sometimes memory count then just flashing curser, then I believe 2 beeps if I wait a minute or so.
When the memory count only went as high as 256K, that was because the RAM on the Quadboard could not be seen by the motherboard.I swapped the cards around and get mixed results.
I ordered some Deoxit. I think my connections are dirty on the boards.
Just a question....
Why does this XT have 2 floppy cards. Long one looks like IBM, then its jumped to a smaller one, then that goes to floppy drive?
I believe the smaller card isn't a floppy controller, but is instead a Transcopy board, aka the Central Point Option Board. It was used to make backup copies of copy-protected diskettes. It sits in-between the floppy controller and the floppy drive, and is cabled to both. Since this is your first PC experience, just remove the smaller card and hold onto it until such time that you need to make backups of copy-protected diskettes.

What exactly are the symptoms?
A few seconds after the RAM test finishes, expect to see/hear:
* The LED on the floppy drive flashes on
* A noise when the floppy drive's spindle turns
* A noise when the floppy drive's heads move to track 34

That sounds to me like your IBM 5160 is booting; there's just a lack of video.So I turned on the PC this morning.
No cursor, no memory count. HDD is spinning.
Then about 45 seconds later 1 beep and floppy was accessed.
The status light on the HDD blinks a few times after floppy drive was accessed.
I left it running for 5 more minute and nothing.
No point now, unless you sometimes hear something that you believe is '2 beeps'.I tried uploading the audi, but site wont accept .m4a format
1. If you remove the Quadboard, the 45 seconds will reduce a lot, because the POST has less RAM to test.
Hi mate, you configured XUB for generic multi-io card. You can fix it. This looks like blue lava xt-cf deluxe. I have it, and I kept the files that came on 64MB CF card that came with it.
If you can copy the files to a bootable floppy, you can boot from it, just press A when XUB comes up.
If you can't copy files to a bootable floppy, but have an EEPROM programmer, like MiniPro, you can burn the file to a 28c64 chip directly.
Use IDE_XTP.BIN only if you use NEC V20 CPU. Use IDE_XT.BIN if it's normal 8088.
When you see the XUB's hotkeybar, press the 'D' key. That will make the XT-IDE's drive become the first hard drive, and the MFM drive become the second hard drive. The 5160 will then boot from XT-IDE's drive (the first hard drive), with the XT-IDE's drive presented as logical drive C:, and the MFM drive presented as logical drive D:Then it boots from HDD .
How do I access the XTIDE ?

Assumption: The purpose is to make a backup of the MFM drive.Will I need a special program to copy contents of original HDD to CF?
In the following, DEBUG is used to copy the contents of U18 into a file named MYF800.BINThe "1501512" on U18 confirms a revision of 11/08/82. I guess that the contents of your 1501512 differs slightly to my 1501512. I will do further research on that.
