computer will appear unstable phenomenon. This is due to the limitations of the INTEL850/850E chipset, and Intel recommends that the number of chips per memory be ≤ 24. And the current domestic sales of Rambus 256 memory chip number is 8, RAMBUS512MB memory of the number of chips is 16, so when users use too much memory is likely to appear unstable phenomenon.
6. Make large memory a hard drive
If you have more than 512MB of memory, and there is a new one or an
large-capacity hard disk is preferred, and some users think that this type of hard disk is technically mature, stable, so also choose this type of PATA hard disk.Composed of Intel, Dell, Seagate, Maxtor, and Apt, serialata.org, introduced new technology specifications for hard disks, serial ATA, serial interface, and Seagate announced the serial ATA 1.0 standard at the IDF Fall 2001 Conference, Officially announced the establishment of SATA specifica

var products1 = Solr. Query (New Solrquery ("Lucene")); Search for ' Lucene ' in the default field
var products2 = Solr. Query (New Solrquery ("NAME:SOLR")); Search for "SOLR" in the "Name" field
2. Query by Field
This allows your to define field name and value separately:

var products = Solr. Query (New Solrquerybyfield ("name", "SOLR")); Search for "SOLR" in the "Name" field
It also has the benefit that it handl
space to hide the bad road in the sector, saving us valuable hard disk space.
The third recruit: low lattice
If the hard drive is more bad and cannot be repaired, consider the low grid. Tools can be used with Maxtor Lformat. Although the low lattice on the hard drive has some damage, but it can solve most of the hard drive bad road problems, so that your hard drive back to the dead. Copy the Lformat to the boot disk, use this disk to boot to DOS
Sata's full name is serial Advanced Technology attachment (Serial Advanced technology Attachment, an industry-standard serial Hardware driver interface), which is made up of Intel, IBM, Dell, APT, The hard disk interface specification proposed by Maxtor and Seagate Corporation. The Serial ATA 1.0 specification was formally established in 2001 by the Serial ATA Board of Intel, APT, Dell, IBM, Seagate, and the major vendors.
SATA support Ho
SATA devices are becoming more and more popular, including the stat hard disk and optical drive are basically SATA interface, the previous old power output interface is generally 20 pin for the motherboard plus 4-pin power supply for the hard drive that is, the previous computer power supply to the hard drive without the design of 15-pin SATA interface power supply, now SATA power supply is 15-pin, then we have no way to use the old power supply to drive the new equipment now.
