IBM 5155 help

If the drive is accessible and not booting, that generally means you need to run "fdisk /mbr" on it. thats on the floppy disk i sent, so you can give that a go (just run from the floppy, you don't to target c: or anything). Then you could try booting off the cf card once more.
 
I plan to go to a pc store later today to see if they have the cleaning materials (i only have like two of them). In the mean time i've been seeing if i can get dos applications running since i can boot ms dos from B drive and access the CF card. Still no luck booting but also no luck opening files/programs. The files are accessible but cannot be opened (could be a compatibility issue with the files since i'm not entirely sure what works).
So....

"MONOPOLY.TXT" is a text file. You proved that by displaying it with DOS's built in "TYPE" command. In order for "FOPEN MONOPOLY.TEXT" to work, you'd need an executable file named "FOPEN" that can do something reasonable with a text file either in the current directory on the "C:" drive or somewhere it can be found when DOS looks for it in the places specified in your PATH environment variable. Typing "MONOPOLY.COM" would likely work if it was a valid executable .COM file. So two of those three errors would have happened even if your CF card was working correctly.

IOW. part of the trouble you're having is your inexperience with DOS, and part with hardware the may or may not be working properly.

You might want to back off and try to get some of your stuff figured out on a real DOS machine, or an emulation of one on VIRTUALBOX. I'd avoid DOSBOX because in my experience, their incomplete emulation had me chasing troubles in shell scripts that were caused by DOSBOX, not my crappy programming.

A good place to brush up on your DOS skills.

ok, i did /fdisk mbr and i did get a different result when formatting C. It did however give me an error message. Seems there's a "bad partition table"

I don't think you necessarily needed to format C again, you can use "fdisk /mbr" and it won't mess up the contents of your hard disk/CF card like the normal fdisk does.

That said, "bad partition table" is consistent with what fdisk is supposed to fix. You may need to run fdisk again, then maybe do the "format c: /s" again on top of that. Well, i suppose you can try just doing "fdisk /mbr" and rebooting, but i suspect you may need to do the whole process from the start again.

i did just /fdisk mbr and just rebooted but it said it couldn't find the OS. this is me redoing the whole process. I will do it from the start again to see if thigns change
 
OK, got it. It's hopeful to see the floppy disk is working long enough to run some programs though.
Honestly I'm leaning towards another incompatible CF card at this point. I finally found my 64 MB cisco CF card here, which i think would be compatible. (Most of my 512 MB cf cards I have I know do not work right with XT-CF adapters.
If that doesn't work out for you I can mail you this one tomorrow.

idk, i've been trying everything i can to get it to boot, and honestly the computer only reads the cf card half the time

This is the process I went through this time, says missing OS. It really seems no matter what I do i get an error

Someone has sent me a cf card that has dos on it and it boots, it was probably user error though i wish i know what it was i did wrong. Thanks everyone for helping me learn how to access/use the computer. I'm able to put things on the cf card and run them, and i'm going to try writing to floppy disks soon
 
Glad to see the CF card works. It's one I had lying around in an XT clone, so it may have some random drivers, etc loaded, but you can mess around with autoexec.bat and config.sys and clean it up if necessary.

Good luck with the floppy disks. One thing to keep in mind with 5 inch disks is that 1.2M and 360 K floppies can't really be used interchangeably.
As you start to mess around with the machine more you may eventually find 2M-XBIOS useful if you wish to use a 3.5" drive and 1.44 MB floppy disks (which are the easiest to find.)
