Hi Friends,

Am installing FreeBSD 7.0 on an AMD Athlon XP 2000 | 256MB RAM | 80GB HDD

Am not able to enter Install mode using FreeBSD 7.0 Disk1-i368

The Error message is :

acd0: FAILURE READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05
Manual root filesystem specification


Am sure that the CDROM and CDRW Drive Works 100% Perfect; because
it works fine in other machines !!!

i gave a try by disabling DMA in BIOS
also attempted to set hw.ata.atapi_dma=0 (by escaping to loader prompt;
googled and found this; i dont know what it is)

No away !!

if any one have  a solution; please help;

or help me how to search in this mailing list for any such previous post

Thanks in Advance ;)
