I have an ASUS Pundit-R chassis with an integrated ATI RS300 based motherboard. The IDE controller is detected but only as a generic controller: atapci0: <GENERIC ATA controller> port 0xff00-0xff0f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 20.1 on pci0 ata0: channel #0 on atapci0 ata1: channel #1 on atapci0 .... acd0: CDROM <ASUS CD-S500/A/V2.1H> at ata0-slave UDMA33 ad2: 114473MB <ST3120026AS/3.18> [232581/16/63] at ata1-master UDMA33 ... The above Seagate hard drive is connected to the SATA connection, but is probed as UDMA33. Performance is poor (about 15MB/s read). I've also tried a PATA Seagate drive connected to the PATA connector, which was also probed as UDMA33, and performance was much better (about 30MB/s read). Here is the pciconf output for the IDE controller: host# pciconf -vl ... atapci0@pci0:20:1: class=0x01018a card=0x81081043 chip=0x43491002 rev=0x00 hdr=0x00 vendor = 'ATI Technologies Inc.' device = '??? ATA Controller' class = mass storage subclass = ATA ... I believe that this controller requires explicit support. Anyone know anything about IDE on the ATI RS300? The SMBus interface is also doesn't attach: none1@pci0:20:0: class=0x0c0500 card=0x81081043 chip=0x43531002 rev=0x18 hdr=0x00 vendor = 'ATI Technologies Inc.' device = '??? SMBus Controller' class = serial bus subclass = SMBus I think SMBus is quite standardized, so this might be as easy an adding an id? none5@pci2:12:1: class=0x050100 card=0x05101524 chip=0x05101524 rev=0x00 hdr=0x00 vendor = 'ENE Technology Inc' device = '??? PCI Memory Card Reader Controller' class = memory subclass = flash I thought that a PCI based memory card reader would be fairly standard, but I guess most people use USB based readers. This is a 4-in-1 reader/writer for MMC/SD/MemoryStick/xD. Anyone heard of these two controllers before? Tom
