Hi,

How much memory is required to install Debian (3.1 and 5) on an Indigo2? I have 128MB and get this when I attempt to install:

tip22: IP22 Linux tftpboot loader 0.3.8.6
Loading program segment 2 at 0x88002000, size = 0x218000 Zeroing memory at 0x8821a000, size = 0x365b0 Starting kernel; entry point = 0x881e0040
Copied initrd from 0x88aab190 to 0x88251000 (0x1d5ce2 bytes)

PANIC: Unexpected exception

It looks like the kernel is loading at 0x88002000 which is more than 128MB away from the beginning of kseg0.

Thanks,

Chris Rhodin

Yes and that's correct. Memory doesn't always start at address zero!
