[newbie] bus speed
Since updating, I have seen that my transfer rate between partions has dropped to roughly 2 - 3 Mb/s, I was getting over 10. On bootup, moving to verbose output ,it tells me that the bus speed is 33mhz... I believe it was set at 100mhz. in Hardrake, it doesn't seem to allow me any options to alter this. How do I do it? Before anyone says anything, yeah, I'm a complete prat :-) -- [EMAIL PROTECTED] Broadband for Doon Valley It's a Reality!!! Penquins ahoy! Want to buy your Pack or Services from MandrakeSoft?

Most likely you do not have DMA enabled on your Hard drive.
Install the hdparm package then open a root terminal
hdparm -i /dev/hda (assuming the drive is hda )
will tell you the transfer modes supported by the drive, and the mode in use
will be marked with an asterix as shown in my case here:-
[EMAIL PROTECTED] download]# hdparm -i /dev/hda
/dev/hda:
Model=IC35L040AVER07-0, FwRev=ER4OA44A, SerialNo=SXPTXF74826
Config={ HardSect NotMFM HdSw15uSec Fixed DTR10Mbs }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=40
BuffType=DualPortCache, BuffSize=1916kB, MaxMultSect=16, MultSect=16
CurCHS=4047/16/255, CurSects=16511760, LBA=yes, LBAsects=80418240
IORDY=on/off, tPIO={min:240,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=yes: disabled (255) WriteCache=enabled
Drive conforms to: ATA/ATAPI-5 T13 1321D revision 1:
* signifies the current active mode
You can use hdparm to change the transfer mode (see man hdparm), but it is
actually easier to just edit the file /etc/sysconfig/harddisks
uncomment the transfer mode you wish to enable. (You need to reboot before the
edits become active)
The command
hdparm -t /dev/hda
will measure your disc transger rate for you.

You don't want to. It's already correct. 'less /usr/src/`uname -r`/Documentation/ide.txt' (give it a read) The idebus is the pci bus, not to be confused with ATA speeds. Which also run on the 33.3 Mhz PCI bus. run (as root) 'hdparm -v /dev/hd?' (where ? is the drive letter you want to check) It should look somethin like this # hdparm -v /dev/hde /dev/hde: multcount= 16 (on) IO_support = 1 (32-bit) unmaskirq= 1 (on) using_dma= 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead= 256 (on) geometry = 65535/16/63, sectors = 160086528, start = 0 The first 4 are the more important ones. -- Tom Brinkman Corpus Christi, Texas Proud to be an American Want to buy your Pack or Services from MandrakeSoft?

[newbie] Bus speed: Dumbdumbdumb question
I have a new motherboard. It asks do I want to set it for "host bus speeds" ranging from 60mhz to 100 mhz. I am going to install a Pentium 233 MMX chip now. In two weeks, I will replace that with an AMD 400 mhz cpu. Now, do I set the bus speed at 60 or 66 mhz for the 233? And don't I set it at 100 mhz for the 400mhz cpu? I checked Intel's web site for the pentium but it offered no advice. thanks much, Steve Winston _ Do You Yahoo!? Get your free @yahoo.com address at http://mail.yahoo.com
Re: [newbie] Bus speed: Dumbdumbdumb question
233mmx = 66mhz 2.8v and yes, you will set it at 100mhz for the 400 Bill - Original Message - From: Steve Winston [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, June 14, 1999 12:20 AM Subject: [newbie] Bus speed: Dumbdumbdumb question I have a new motherboard.
