TP 600,770/ED - Fatal exception error or system locks-up when greater than 190MB memory is installed
Applicable to: World-Wide
Symptom:
On ThinkPad 600 and 770/ED, Fatal Exception (0E) occurs during the booting of the machine.
Configuration:
ThinkPad with internal ACP modem without the v.90 upgrade and greater than 190MB memory is installed. For example, a 128MB DIMM installed in slot 1 and 2 or a combination of a 128MB and a 64MB DIMM are installed.
Note: Not all ThinkPad 600's and 770's come with an internal ACP modem.
Workaround:
Remove RAM in the system so that the maximum amount of RAM installed is less than 192 MB of memory.
Solution:
The IBM 128MB SDRAM DIMM option includes a diskette, "ThinkPad ACP Patch for ThinkPad 600, 770, and 770ED" which will fix this problem. Also updating the ACP modem code to v.90 will correct the problem.
To download the latest version of the v.90 code for Windows 95/98 and NT, please click

Additional information:
Maximum memory recognized will vary by machine based on hardware limitations. Also supported memory technology may vary by machine type. Refer to the specifications for the specific model.
