| |
Hello, I've recently experienced a problem with hd geometry on Linux kernel 2.2.17. I've got 2 identical hard drives, set up as LBA on BIOS. BIOS sees them both with geometry 1245/255/63, while Linux sees the second one as 19857/16/63. I know i can force the kernel to recognize the right geometry using lilo's append=... feature, but I cannot realize why this is happening. I've tested it ONLY on Asus motherboards (p2bf and p2b with latest BIOS version), so maybe this can be a simple hardware problem... Anyway here's a snip from the dmesg:
hda: FUJITSU MPF3102AH, ATA DISK drive hdc: FUJITSU MPF3102AH, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: FUJITSU MPF3102AH, 9773MB w/2048kB Cache, CHS=1245/255/63, UDMA hdc: FUJITSU MPF3102AH, 9773MB w/2048kB Cache, CHS=19857/16/63, UDMA
Now the OS version: seti:~# cat /proc/version Linux version 2.2.17 (root@seti) (gcc version 2.95.2 20000220 (Debian GNU/Linux)) #2 Fri Oct 20
If I switch the 2 hard disks the one put on the secondary IDE channel has CHS=19857/16/63, no matter which one is, while the first one remains with 1245/255/63. Let me know...
Cheers, :raptor
