Hello developers,
running recent 2.4.20-preX and -ac kernels I'm getting weird
CHS infos about my ide disks on the primary onboard IHC2
controller:
Kernel 2.4.20-pre8, or 2.4.20-pre7-ac3 both:
ICH2: IDE controller at PCI slot 00:1f.1
ICH2: chipset revision 2
ICH2: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0x9800-0x9807, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0x9808-0x980f, BIOS settings: hdc:DMA, hdd:pio
PDC20268: IDE controller at PCI slot 02:0d.0
PCI: Found IRQ 9 for device 02:0d.0
PCI: Sharing IRQ 9 with 02:09.0
PDC20268: chipset revision 1
PDC20268: not 100% native mode: will probe irqs later
ide2: BM-DMA at 0xa400-0xa407, BIOS settings: hde:pio, hdf:pio
ide3: BM-DMA at 0xa408-0xa40f, BIOS settings: hdg:pio, hdh:pio

I started to use pre7-ac3 because its drives well my
PDC20268 in UDMA100 instead of UDMA33 as in pre-8.
When I'm appending the correct CHS with lilo it works fine,
but why its not autodetected?
hda: IC35L060AVVA07-0, ATA DISK drive

ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
ide2 at 0xb800-0xb807,0xb402 on irq 9
ide3 at 0xb000-0xb007,0xa802 on irq 9
Also discovered, that mke2fs see different block numbers on
the PDC20268 as on the onboard (Asus TUSL2-C) controller:
mke2fs 1.26 (3-Feb-2002)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
7520256 inodes, 15012734 blocks
750636 blocks (5.00%) reserved for the super user
First data block=0
459 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
On PDC I get:
mke2fs 1.26 (3-Feb-2002)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
7520256 inodes, 15012892 blocks
750644 blocks (5.00%) reserved for the super user
First data block=0
459 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Again, why?
