You have managed to make your machine unusable. I know how to get your machine to boot from floppy but the procedure requires that you be able to boot the VRM. You aren't getting that far. Your only recourse is to disconnect the battery and re-install the VRM after letting NVRAM forget about what you put there. The battery is inside the front panel. You essentially have two problems. One is that NVRAM won't let you boot from diskette, and the other is that you aren't getting anything booted from the hard disk either. Yuk. I would have emailed but I consider myself to be an authority on this question. -- James Moody aesnet:moody@moody.austin.ibm.com Advanced Workstations Division vnet: MOODY at AUSVMQ Austin, Tx zip:3401
