Accordingly, it may contain significant errors — and corrections are greatly appreciated. Model ARC has a battery backup unit option. I am still trying to untangle references to SiI’s model numbers. If your installer finds no block devices or has other problems, please realise that all Linux SATA support is still hit or miss. This turns out to be a Silicon Image variant or A-variant. Temporarily add a PATA drive to your system.

Don’t assume this page’s via vt6421 raid controller are perfect. Accordingly, it may contain significant errors — and corrections are greatly appreciated.

Promise offers a ” ftsata2 ” proprietary driver open-source wrapper around a binary-only, proprietary via vt6421 raid controller library. This image uses a 2. If your installer finds no block devices or has other problems, please realise that all Linux SATA support is still hit or miss. Model ARC has a battery backup unit option. Linux often cannot read existing fakeraid volumes on such host adapters, unless you’re willing to use proprietary fakeraid drivers where available.

SATA can theoretically do tagged command queuing TCQbut support for that feature is just now under construction in libata — and exists in none of the other Controoler driver sets.

Switch the BIOS setting back. A file of hints on via vt6421 raid controller the gdth driver with sundry distributions is available from ICP Vortex. Alternatively, Alan Cox’s series of -ac variant kernel source code trees include an ” it ” driver as Alan’s add-in to 2.

Rebuild your installer using kernel 2.

Serial ATA (SATA) on Linux

via vt6421 raid controller Garzik posted a patch on to support this device; the code will be included in kernel 2. Strings within Silicon Image’s proprietary drivers suggest that bt6421, e, and 4e4e are chipset model numbers with the following “subdevice” numbers in their respective families.

Uses the sarge “debian-installer” d-i installation routine and via vt6421 raid controller 2. A patch may be necessary to run this driver properly on newer 2. Contrary to popular belief, it includes low-level drivers for many common SATA chipsets. The iswraid patch will be merged into kernel 2. Driver is now production quality.

This entry is a placeholder. No libata driver exists for these, but Alan Cox is working on one as of There are individual low-level drivers for the individual SATA chipsets, e. Article by Karl Schmidt, via vt6421 raid controller which he uses the Debian-sarge beta4 installer’s 2.

Correspondent Andreas Thienemann warns that this driver works on Linux 2. Alternatively, LSI has produced proprietary, binary-only drivers source raic wrapper accompanying a via vt6421 raid controller binary-only driver for ICH6-R.

Serial ATA (SATA) chipsets — Linux support status

There are three workaround options, if your installer still has a problem with support via vt6421 raid controller the SATA chip present: Cards use Marvell chips. Development code can be retrieved via rsync: Fedora custom CD construction — creating your own custom Fedora-based installer starting from via vt6421 raid controller stock Fedora image, e. VTM South Bridge chipset. Per the libata report, a separate block driver, “sx8” not part of libatahas been written for this hardware.

The cheaper and cards differ from their and brethren in having some advanced capabilities disabled; they can be upgraded via an extra-cost software key. Card disables the drive’s write cache.

This is because many SATA host adapters, like ATA generally absent special hardware provisions, simply don’t support hotplug functionality. Install Linux onto that.

Optional battery backup unit is available for the model card’s cache, for more reliable operation in the event of power loss, etc. RAID issues a separate wrinkle: One source says these cards are based on Silicon Image chips, which are probably not the system-facing chipsetsand so don’t determine driver support. Optional battery backup unit is via vt6421 raid controller. This via vt6421 raid controller to to be a Silicon Image variant.

The Broadcom chip used appears not to be model BCM, so Broadcom’s proprietary “bcraid” cotnroller likely won’t work. Uses a Silicon Image chip.

These are rumoured to be a cheap OEM from someone else, but the chipset identity is unknown. Alternatively, use the manufacturer’s GPLed driver code. Cache memory add-on hardware module is available for some models OEM versions only, though, not retail.


Compatible with Linux’s megaraid2 driver. Probably supports the standard AHCI driver interface unconfirmed.
