37GB IDE disk a Linux

[Petr Soucek]

Zdravim,

narazil jsem na problem s 37GB IBM IDE diskem. Kernel ho nadetekuje
spravne, ale fdisk i cfdisk vidi jen 3GB. Ve stejnem stroji mam i IBM
IDE disk 17GB a ten je v pohode. Je to RHL6.0 s jadrem 2.2.10-ac8.

PIIX3: IDE controller on PCI bus 00 dev 39
PIIX3: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:pio, hdb:pio
    ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio
hda: IBM-DTTA-351680, ATA DISK drive
hdb: IBM-DTTA-351680, ATA DISK drive
hdc: IBM-DPTA-353750, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: IBM-DTTA-351680, 16124MB w/462kB Cache, CHS=2055/255/63, (U)DMA
hdb: IBM-DTTA-351680, 16124MB w/462kB Cache, CHS=32760/16/63, (U)DMA
hdc: IBM-DPTA-353750, 35772MB w/1961kB Cache, CHS=7144/16/63, (U)DMA

fdisk pise:
Disk /dev/hdc: 16 heads, 63 sectors, 7144 cylinders
Units = cylinders of 1008 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hdc1             1      7144   3600544+  83  Linux

z toho CHS=7144/16/63 se zda, ze je disk v CHS a ne LBA modu. A zrejme
pocet cylindru je 65536+7144, ale linux to orizne na 16 bitu. Jak ho ale
do toho LBA modu dostat? BIOS ho nenajde.

Nebo mate nejaky jiny tip? 

Zdravi
