6421+ based SATA cards are a popular and inexpensive way to add SATADrives to the IDE system. While SATA – IDE SATA ConverterFrom peripherals to IDE controllers, these cards offer a number of benefits:
– Adds LBA48 compatibility with older motherboards.
– Add SATA compatibility for new cards that do not have IDE a. decidedcompatible chipset or SATA.
– Add eSATA depending on the card.
In these cards, the most important thing is that I have themFor Windows 95 use VIA driver for now!
There is a small problem with the installation of the main driver of the VT6421 raid controllerunder Win95. Windows 97 treats the card as a hard disk class controller,while Windows 98 / ME considers it to be a SCSI class controller. How is Win95 productionwill think the INF file contains fewer correct drivers.
To install the generic Win9x driver b For changes, add most of the driversmanually by starting the Add New Hardware Wizard from the control paneland choose to actually check for new material. From the list of related equipment types,select “SCSI Controller”. In the list of known drivers, click Have Disk.and go to the Win9x folder of your ViaRaid driver. Then choose yourSpecific mastercard (Raid VIA VT6421 controller). Go to helper typecopy and install the drivers but they are not linked yetwith this card.
Then find the 6421 card, which I would say in device manager. Probably, bepresented as “unknown device”. Open the driver, I would say properties, and clickUpdate your driver. Select a driver from the list, so click Next.then click Back immediately. Now you can see a list of SCSI hardware types,Select your controller, then Show All Hardware. Select VIA 6421Close the driver from the list and, alternatively,
or edit the INF file to set “Class = hdc”. Line- Actually relevant, – commented. Just uncommentf this andComment out “Class = SCSIAdapter”.

The VIA 6421 prompts I tested are annoying that theyall seem to ship with older BIOS versions with bugs. Although theyworks, BIOS 4.x always clearly displays the message “For RAIDIf you want to install Linux Standard Partition RAID Driver, DO NOT!Use the OPROM creation operation! “When the engine starts.
After studying the seemingly eternal exploration and then reading the postPost who couldn’t even do it, I finally found Flash BIOS updaterfor this chip.
Please note that some Via 6421-based cards may not have a motorboat with a BIOS chip at all.and could have other EPROMs that are not fromFirmware utility. Despite the fact that this daphnia is built on a motherboard, it costs someonePlease use the BIOS update program provided by your motherboard manufacturer.

In addition, the following changes have been made to this original.Memphis version:
- Removed the warning that the beep was heard when connecting small drives. This usefulnessRecovers as a dedicated eSATA card for removable media.
- Fixed a lot of incorrectly translated English from VIA.

This problem can be “solved” by setting – the PCI register in the 6421 controller.

Of course, you can manually work around this issue using a utility.as WPCREDIT to successfully set PCI register 0x52 LSB 2 of 6421 (fromFrom zero) to “1”.

If you plan to use external eSATA devices with 9x, the first drive lettersthere might be a problem. Connecting a single drive may result in drive letters being followed. ElementaryPartitions are assigned the first drive letters so they can be recognized.BIOS then extended partitions to recognize accurate driveson bios.
One way to solve this problem is to use a 6421 card that does not have one. haveBIOS (these cards are not bootable and cannot be used under DOS). Advantageif DOS has not seen the disk since then, the socket letter is not “pinned”and Windows can assign any drive letter to it, just like it does with USB drives.
Another way to solve the problem is to place the entire partition of the current removable disk.Drive in an extended section. Thus, as a partition on a removableThe drive should be sent to drive letter after all those dealing with partitionsfirst trip.

RAID
Function 6421 is implemented in the driver using the PC software, anddoes not work on all operating systems. I would never bother with this taskI’ve tried. If you need RAID, get a hardware RAID card, which often makes an arrayUse a transparent for the operating system and / or optionally supplied with software RAID in an available copy.
Other options: Vantec CB-SP200 with dual SATA and IDE ports orIts manufacturers of single-port converters are ideal for connecting new SATA hard drives.and CD-ROM drives on the existing IDE port.
