CD-ROM Error

Asked by Jamie

Trying to install Server 7.04 on an IBM eServer xSeries 360. During install or a check check get the error: ".../install/initrd.gz failed the MD5 checksum". Have tried it on two other identical servers, with the same result. However the same CD is fine on a Sony laptop.

In final? The last test is on the Sony laptop's optical drive?
The CD is not damaged in an IBM server's optical drive?

I do the test with fsum 2.52.00337

BUT ***THIS*** IS ERROREUS, the ISO is GOOD

I checked with OpenSuse 10.2, and with boot in a PC (with DVD-RW drive)
