Hello!
Here we go again... regarding a change off boot devices that I was
trying to do, I started with that setup (I'm using LM8, Linux LM8 is
kernel 2.4.2-20mdk):
/dev/hda (master at IDE0) : 40G Quantum HD, with Win98
/dev/hdb (slave at IDE0) : 4.3 WD HD, with Linux LM8 - ReiserFS
/dev/hdc (master at IDE1) : Creative Labs CD-ROM CDRW 4224
What I wanted (Quantum is ATA 100, WD is ATA33, is slowing my
performance a little):
/dev/hda (master at IDE0) : 40G Quantum HD, with Win98
/dev/hdc (master at IDE1) : 4.3 WD HD, with Linux - ReiserFS
/dev/hdd (slave at IDE1) : Creative Labs CD-ROM CDRW 4224
I had lots of problems when (trying to) changing these devices... erros,
messages of CRC errors... until I noted that when the CD-ROM wasn't
connected at the same IDE that the Linux HD, the system worked...
Is this a bug? If it is... is from Linux, or from ReiserFS? Can be
corrected? Below are some lines from /var/log/message (relevant parts
are marked with ***** below the line of the error):
Jun 15 20:08:53 orlando kernel: ide: Assuming 33MHz system bus speed for
PIO modes; override with idebus=xx

By the way... how can I change this??? I want to put my IDE at 66MHz...

/dev/hda and /dev/hdc are recognized... note that there is no /dev/hdd,
the CD-ROM was with the power cable disconected, but the IDE cable
attached to it caused that mess:

Everything goes ok from here...

/dev/hdb (slave at IDE0) : Creative Labs CD-ROM CDRW 4224
/dev/hdc (master at IDE1) : 4.3 WD HD, with Linux - ReiserFS
as a workaround, the thing goes ok:

What those messages mean??? Can I fix this???
And beyond that all works fine too...
I'm using Soyo SY-6VBA 133 (Via Apollo chipset)... I don't know if it's
relevant... but is one more info... by the way... my CPU is a Celeron
400MHz, overclocked to 540MHz. My system memory is 160MB (three modules,
128M, 64M and 32M)... Linux LM8 is kernel 2.4.2-20mdk...
TIA
