Re: Asus P5VDC-X Motherboard -- can't get it to boot

A built a custom kernel with the IDE components built-in, and the system has finally come up.

My problem now is the disabled DMA for my hard drives -- makes the quite slow.

Re: Asus P5VDC-X Motherboard -- can't get it to boot

Mine is slow booting (P5B) not checked dma or hdparm yet....

errr

 hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   3704 MB in  2.00 seconds = 1852.39 MB/sec
 Timing buffered disk reads:  216 MB in  3.01 seconds =  71.77 MB/sec

Not suer if thats ok nothing to compare it with ....

Are you like in Arch yet....?

mkinitcpio is easy to use .....

Maybe chroot in & fix your problems (what I had to do when swappin' drives!)

Cannot think of anything else  roll

Re: Asus P5VDC-X Motherboard -- can't get it to boot

Yup, got it to boot.  I found a patch for my chipset so it recognizes it and allows DMA.

In comparison to yours above, I'm getting 2Mb/s compared to your 70Mb/s  :shock:

The bottom line, the IDE pieces must be compiled in for my system to boot.  I still have a boot image from mkinitcpio as well. 

I'll find out soon if this little patch fixes my speed issue.

Re: Asus P5VDC-X Motherboard -- can't get it to boot

Ok, here it is.. what an improvement for an old hard drive I'm using --

Before kernel patch:

hdparm -Tt /dev/hda

/dev/hda:
 Timing cached reads:   2292 MB in  2.00 seconds = 1146.17 MB/sec
 Timing buffered disk reads:   10 MB in  3.57 seconds =   2.80 MB/sec

after:

VP_IDE: IDE controller at PCI slot 0000:00:0f.1
PCI: VIA IRQ fixup for 0000:00:0f.1, from 255 to 0
VP_IDE: chipset revision 7
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt8237a (rev 00) IDE UDMA133 controller on pci0000:00:0f.1
    ide0: BM-DMA at 0xfc00-0xfc07, BIOS settings: hda:DMA, hdb:DMA
    ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:DMA, hdd:pio
Probing IDE interface ide0...
hda: Maxtor 53073H4, ATA DISK drive
hdb: SAMSUNG SV1022D, ATA DISK drive

hdparm -Tt /dev/hda

/dev/hda:
 Timing cached reads:   2408 MB in  2.00 seconds = 1203.09 MB/sec
 Timing buffered disk reads:   92 MB in  3.05 seconds =  30.15 MB/sec

Looks like I'm back on track!

thanks all.
