You can't change the IDE bus speed. It's set to 33Mhz (66Mhz if you have a MBrd with 64Bit slots). The 266Mhz bus speed you are refering to is the CPU-Memory Bus, and the board will run at that speed without problems. However the IDE bus TRANSFER rate can be changed using hdparm (--help for parameters) Wolf -----Original Message----- From: Christopher Taylor [mailto:psychocop156@insightbb.com] Sent: Sunday, 1 December 2002 11:54 AM To: psyche-list@redhat.com Subject: IDE Bus Speed In reading the boot information for my RH8 system, I noticed that the system defaults to 33MHz. It also says to set it using IDEBUS=XX. Where do I set it at (I assume in grub.conf, correct?) and what are the limitations of it (i.e. I've got a 266 MHz system bus....can I set it that fast?) Any input would be greatly appreciated.....just learning Linux, and need to tweak the machine out for UT2K3. Thanks in Advance!
