Gigabyte Technology issued a BIOS update on Friday that fixes a problem for some Windows 7 users who have been unable to sync their iPhones.

Earlier this week, Intel, Microsoft and Apple said they were investigating the issue, which people are complaining about on an Apple forum. The problem seems to be mainly affecting Windows 7 64-bit users with Intel P55 chipsets, and it prevents them from synching their iPhones with their computers.

On Friday, a few people posted on the forum that they'd downloaded the new BIOS from Gigabyte, a motherboard maker, and it solved the problem. In the description of the update, Gigabyte calls it a Beta BIOS and says that it fixes the iPhone sync issue, among other enhancements.

The BIOS update will help people who have the Gigabyte motherboard in their systems, but it won't help other people who have the problem, such as those with an Asus motherboard.

Earlier this week, Microsoft also said it was looking into the problem and recommended that people visit its help page for updates. It does not appear to have posted any information there and did not immediately reply to a request for comment about the Gigabyte update.

Though an Apple employee asked people on the forum to send details of the issue, it does not appear to have posted further information about the fix yet.

Intel said it could not comment on the Gigabyte BIOS update.
