Lanplex 2500 image problem

[PA1GS]

I've installed a new image on the Lanplex 2500 (internal flash, no flashcard), but somehow it isn't working ok anymore. After startup it continuesly repeats the message :

Spurious Bus Error Interrupt
023FFF5C - Stack pointer
00002700 - Status register
000055A4 - Program counter
0000C008 - Vector offset

Uart Test Passed
Setting Stack at 023FFF5C
Port A Reg. = 000000E0
Ram Detected = 00400000 Bytes

Mode = Reset
Setting Stack at 02400000
Stack Enabled
Flash Boot Parameter Block: 0x81dc
Flash System ID Block: 0x81b8
PCMCIA Card Not Detected
68340 Status Reg. = 0x7b
Moving text from 0xa0020, to 0x2490000, size 0x2f94

Is there a way to reinstall the old image on the system.

Thank you for reading this message.
