ultra-ata hard-drive installation

OmniBong · 01-13-2003, 10:24 AM

I am trying to install a new maxtor ultra-ata hard-drive into my system. I have an ASUS A7V motherboard with ultra-dma support. I also have a 900 MHz processor with 512 MB of RAM (133MHz). I'm trying to configure my system to use 133MHz on the bus. Presently the /var/log/boot.msg file reports that my bus speed is 33MHz.

How can I make sure that my system bus speed is at 100 MHz and above?

The kernel reports a current tuning of 33Mhz at boot, the drive should autodetect and ramp up to whatever it can handle. hdparm will tell you what its really running at. For instance, here's my ATA100 drive:

Code:

root@tyler:/home/bob# hdparm -i /dev/hde

/dev/hde:

 Model=WDC WD400BB-00AUA1, FwRev=18.20D18, SerialNo=WD-WMA6R2754114
 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }
 RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=40
 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16
 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=78165360
 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes:  pio0 pio1 pio2 pio3 pio4 
 DMA modes:  mdma0 mdma1 mdma2 
 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 
 AdvancedPM=no WriteCache=enabled
 Drive conforms to: device does not report version:  1 2 3 4 5

The flag next to udma5 means ultraATA 100, udma6 is 133, I haven't got it as my drive can't even do that, also hdparm just began to account for 133, so depending on whether SuSe shipped a brand spanking new version, it might read funny... most likely your drive is running at the correct speed.

If not, post back, hdparm can tune the speed.
