{101} dmesg | grep "memory ="
total memory = 8190 MB
avail memory = 7932 MB
{102} dmesg | grep wd0
wd0 at atabus0 drive 0: <Maxtor 6L300S0>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 279 GB, 581463 cyl, 16 head, 63 sec, 512 bytes/sect x 586114704 sectors
wd0: 32-bit data port
