Urgent - Single User Mode -Unisys System V Release 4.0

Hello All,

I have a Unisys 6000/65 machine running Unix System V Release 4.0.My problem is that we received an error that said "SPCS error occurred"and "vxfs:vx -ilisterr-inode 62585 mark bad /filesystem".The machine was stuck and I had to restart it.Now I cannot login from any workstation or the console with any user accounts or passwords.How do I get into single user mode?During the boot process you get a message saying "starting unix boot loader" and another shortly thereafter saying "booting unix".Pressing any key at this stage prompts you to choose a kernel to boot.The networking part works fine as you can ping the box but just can't log onto it.

PS:You will be forgiven for not having heard of the Unisys 6000/65 or that version of unix for that matter.

Try booting from the CDrom.
Wild guess is you lost the OS disk.

Thanks for your response.
Machine has no CDROM nor does it have a stiffy drive.It does however have a Floppy drive and a couple of tape drives. and yes I can't seem to find the boot floppy's or tapes.The machine was initially setup in the 90's.
