JMicron Technology Corporation is a Taiwanese manufacturer of integrated circuits.It mostly produces Serial ATA and related controller chips [ [http://www.jmicron.com/Product_list.htm JMicron's product list] ] .

Its chips are used by a number of companies, such as ASUS [ [http://support.asus.com/download/download.aspx?SLanguage=en-us&model=M2V-MX&type=map&mapindex=4 Reference to JMicron on ASUS website.] ] and MSI [ [hhttp://www.msicomputer.com/product/p_spec.asp?model=P965_Neo-F&class=mb MSI's original P965 Neo-F with JMicron controller] ] in PC motherboards, though because of difficulties, newer MSI models have moved to using integrated Marvell controllers [ [http://global.msi.com.tw/index.php?func=proddesc&prod_no=1275&maincat_no=1&cat2_no=170&cat3_no=2 MSI P965 Neo-F version 2, with JMicron controller replaced] ] .

Linux

JMicron SATA/IDE controllers are often incompatible with some boot loaders. In particular, those using GRUB, such as Ubuntu, cannot boot in some conditions [ [https://bugs.launchpad.net/bugs/57502] Ubuntu bug listing of incompatibility with JMicron] . The most recent Linux kernel and the most recent JMicron controller BIOS [ [http://www.jmicron.com/Support_FAQ.html] JMicron FAQ stating newer BIOS software will work with Linux] solve these incompatibilities but may not be present in existing products, requiring a flash of the motherboard BIOS if the newer version contains the JMicron BIOS update. Other bootloaders such as EXTLINUX and the Windows boot loader work fine.
