issues booting with internal SCSI

i bought a second mpc 2k classic that wasnt booting the OS... it has an internal zip 100 on and internal SCSI setup with a 25 pin female SCSI soldered to the main board and sealed plugged to an adapter to a 50 pin IDE cable to connect the zip100... when i power up it scan the SCSI ID's and stops at 5 where it recognizes the zip drive but doesnt boot up.. if i take the disk out it will cycle thru and say "Insert Boot Disk" when i put it in it does nothing.. the disk is formatted from another 2k classic and it booted that machine perfectlly.. anyone think its the SCSI fuse? if so where do i get one? i tried to reconnect a floppy drive but the cable has been removed from the main board so thats not an option unless i find and modify a cable.... someone whos experienced this with and internal SCSI setup please give me your 2 cents...

hmm, does the scsi device have it's terminator attached? and also, you mentioned your have it on scsi ID 5 right? (not on scsi ID 6)

I would suggest getting an external SCSI Zip drive that you can attempt to boot from, since that internal mod doesn't seem to be working at this point.

yeah theres jumpers for the scsi id and for termination on and off... i have the termination on and scsi id at 5 im aware that 6 is the id the mpc sends on...

that was my next guess to try an external zip drive and see what happens i guess if the external drive doesnt work either then ill know if i have a different issue... thanks guys
