Hi Rick, yes, they were burned to 700Mb media (the only CDs one can 
purchase where I buy them). It is apparently a known kernel bug in FC3 
according to the http://www.fedorafaq.org/ web site. Problem is though, 
the workaround supplied by RedHat doesn't work on my machine. MY 
workaround is to load my FC2 CD1 and run the media check from there. 
They all checked OK.

My new problem that prevents me installing FC3 on my machine is as follows:

BUG
Assertion (heads >0) at disk_dos.c:485 in function 
probe_partition_for_geom() failed
96

BUG
Assertion (sectors<=63) at disk_dos.c:490 in function 
probe_partition_for_geom() failed
96

Clicking on the right button (can't remember what it was labelled now) 
resulted in a revolving hourglass cursor and a very long wait 'till my 
patience ran out. Clicking on the 'Ignore' button resulted in aborting 
the install.

I've tried all the boot arguments RedHat has listed at boot time plus a 
couple I saw elsewhere but the error still occurs. It pops up straight 
after selecting the keyboard.

My system is P4 3G, 512 Mb RAM, hda 200G (Win XP SP2 3 partitions), hdb 
40G (FC2), Radeon 9800XXL video and the usual hardware. The system is a 
Medion (German make/design)

Have you heard of this before? If so, what's the workaround?

TIA
