UNIX PC Panic

[A Mayer]

	Last night my UNIX PC decided to stop working.
	I will be grateful for any help.

	The first error message I got was:
panic trap vector 4
type=0x4, pid=40, pc=0x1F6, rps=0x2700, p=0x49F38
GSR=DD00, BSR0=FC00, BSR1=9C3E, PHYSPF=9
D0=70, D1=0, D2=0, D3=0
D4=FFFFFC43, D5=FFFF0000, D6=DD00, D7=70
A1=2FFE64, A1=709DE, A2=400CC, A3=3786B
A4=262E4, A5=92968, A6=70832, A7=2FFE64
panic: trap
please record panic message
press hardware reset to reboot

	The second message is:
#HDERR ST:FF EF:FF CL:FFFF CH:FFFF SN:FFFF SC:FFFF
       SDH:FFFF DMACNT:FFFF DCRREG:F0 MCRREG:8B00
#HDERR ST:FF EF:FF CL:FFFF CH:FFFF SN:FFFF SC:FFFF
       SDH:FFFF DMACNT:FFFF DCRREG:F0 MCRREG:8B00
#HDERR ST:FF EF:FF CL:FFFF CH:FFFF SN:FFFF SC:FFFF
       SDH:FFFF DMACNT:FFFF DCRREG:F0 MCRREG:8F00
panic: iinit
please record panic message
press hardware reset to reboot

	I am able to boot the floppy drive, but not the hard drive.
	I also tryed to reinstall the Foundation Set, but I get
	the second massage above on disk #3 (hard drive boot).

	Is my hard drive shot? Is there anything I can do?

	Thank you in advance,
