Hello everyone, I have a problem with my Averatec Laptop, Freebsd 5.2.1 does not recognize udma100 on my hdd. I've check the bios settings and have set varios options. auto, dma, 32bit mode, and PIO5 (on/off) but i still cant get the drive to work at udma100. the cdrom is in a diffrent IDE channel (1) so I dont think that is the problem. I'm open to any suggestions at this point. after 3 days, my search has led me no where. Jose Lima I tryed to set hw.ata.tags=1, but I get: sysctl: unknown oid 'hw.ata.tags'. my drive is supposed to support this parameter.. http://www.gsp.com/cgi-bin/man.cgi?section=4&topic=ata maybe this is no longer an option on 5.2.1-release ------------------------------- FreeBSD D777123.xxxx.com 5.2.1-RELEASE-p4 FreeBSD 5.2.1-RELEASE-p4 #3: Sun Apr 4 15:10:13 CDT 2004 root@D777123.jlpimp.com:/usr/obj/usr/src/sys/LAPTOP i386 ------------------------------- Dmesg out put ------------------------------- atapci0: <VIA 8235 UDMA133 controller> port 0xfc00-0xfc0f at device 17.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata0: [MPSAFE] ata1: at 0x170 irq 15 on atapci0 ata1: [MPSAFE] ata0-master: DMA limited to UDMA33, non-ATA66 cable or device ad0: 28615MB <IC25N030ATMR04-0> [58140/16/63] at ata0-master UDMA33 acd0: CDRW <QSI CD-RW/DVD-ROM SBW-242> at ata1-master UDMA33 cd0 at ata1 bus 0 target 0 lun 0 --------------------------- Sysctl, DMA Kernel settings --------------------------- ata_request: 168, 0, 0, 48, 52627 hw.ata.ata_dma: 1 hw.ata.wc: 1 hw.ata.atapi_dma: 1 ------------------------------- When I try to change to udma100 ------------------------------- atacontrol mode 0 udma100 biosdma Master = UDMA33 Slave = BIOSPIO ------------------------------------- console output after i use atacontrol ------------------------------------- ad0: DMA limited to UDMA33, non-ATA66 cable or device __________________________________ Do you Yahoo!?
