 |
|
I realized today that system isn't setting the value right
on my grub.conf I have
| Code: |
title=Gentoo1.4
root (hd0,2)
kernel (hd0,2)/bzImage-ga root=/dev/hda8 idebus=66 video=vesa:ywrap,mtrr vga=0x317 hdc=scsi hdd=scsi
initrd=/initrd-1024x768
|
but on boot
| Code: |
Real Time Clock Driver v1.10e
Non-volatile memory driver v1.2
Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH2: IDE controller on PCI bus 00 dev f9
ICH2: detected chipset, but driver not compiled in!
ICH2: chipset revision 4
ICH2: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0xffa0-0xffa7, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0xffa8-0xffaf, BIOS settings: hdc:DMA, hdd:DMA
hda: WDC WD600AB-60BVA0, ATA DISK drive
hdc: Compaq CRD-8484B, ATAPI CD/DVD-ROM drive
hdd: PIONEER DVD-RW DVR-103, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: 117231408 sectors (60022 MB) w/2048KiB Cache, CHS=7297/255/63

Floppy drive(s): fd0 is 1.44M

so it's using 33mhz even thought I told it to use 66. I recall it using 66, but I have no idea when it stopped working (perhaps when I switched to gaming-sources from gentoo-sources, but it should be working anyway
| Code: |
morfismo root # uname -a
Linux morfismo 2.4.20-gaming-r2 #2 Tue Apr 22 10:28:35 CDT 2003 i686 Intel(R) Pentium(R) 4 CPU 1400MHz GenuineIntel GNU/Linux
|
And on a slightly unrelated problem
the /boot partition isn't being umounted when system finishes the startup sequence as it used to
any idea why?
this goes on /etc/fstab:
| Code: |
# <fs> <mountpoint> <type> <opts> <dump/pass>
proc /proc proc defaults 0 0
/dev/hda3 /boot ext3 defaults,noatime 1 1

same here... Even with idebus=66 I get warning 33Mhz on dmesg... gentoo-sources-2.4.20-r1
Anyone?
Thanks,
Norberto |

saludos pibe
well I've read that documtn twice
and I don't quite understand the meaning
what I see it saying is
"hey! don't care about that warning, it's nothign"
but then what was it doing before
when it DID set up idebus at 66
and what it isn't doing now when it tells
it wil assume 33
my point is, if earlier it was choosing 66 and now 33 then somehwere I should be able to make it be 66

What I tried to do is outline what I changed to fix "the error." It still gives me the error too, but if you followed what I did and look just below the message, you'll see it recognizes your drives as what they are (mine = UDMA133)
| Code: |
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
VP_IDE: IDE controller on PCI bus 00 dev 89
PCI: No IRQ known for interrupt pin A of device 00:11.1. Please try using pci=biosirq.
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt8233a (rev 00) IDE UDMA133 controller on pci00:11.1
ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0xd808-0xd80f, BIOS settings: hdc:DMA, hdd:DMA

You're right, however. As the other people in the thread pointed out, it doesn't really matter unless you have 64-bit PCI slots. The "warning" is just because Linux is like every other piece of software is becoming: over-engineered. Not bad, but they're including that check "just in case" someone's running their kernel with a 64-bit PCI slot. |

I think idebus refers to PCI speed (33, 66,) 33 for normal PCs, 66 por 64bit PCI. So messing with idebus can hurt your box (not sure, I better play safe.)
You can now do ide0=ata66 in case your chipset doesn't recognize 80w cables (ide0=hda,hdb, ide1=hdc,hdd...)

| Exactly. idebus has absolutely nothing to do with wether your drives are ATA66 or 100 or 133. It has to do with if your PCI slots are 33MHz or 66MHz. There are no P4 boards with 66MHz slots, so I know your setting is wrong for your board. You could specify idebus=33 to remove the warning, but you really should just ignore it. It has zero meaning for you. |

| So, if I were overclocking, and my pci bus was at 38MHz instead of 33, I should set it to idebus=38? Would that work? I expect that this was originally more useful on some of the early pentiums that had a 50MHz FSB and 25MHz PCI bus. |

On my Fic503+ running the FSB at 112mHz, I set my idebus=37. No need to set ide0=ata33, it gets picked up correctly.
