| |
I have just tried a Pioneer DVD 114, an IDE/ATAPI drive, on my RH6.0 + patches system (2.2.5 kernel). It seems to work properly as a CDROM (all I expected), but the boot log contains an anomaly. Perhaps it is important.
Here is an extract. The interesting thing is on the second last line. It says that the drive speed is 0X. In fact, it is 10X (in whatever way drive makesrs specify speed).
PIIX4: IDE controller on PCI bus 00 dev 39 PIIX4: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:pio hda: IBM-DTTA-371440, ATA DISK drive hdc: Pioneer DVD-ROM ATAPIModel DVD-114 0110, ATAPI CDROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: IBM-DTTA-371440, 13783MB w/462kB Cache, CHS=1757/255/63 hdc: ATAPI 0X DVD-ROM drive, 512kB Cache Uniform CDROM driver Revision: 2.54
A little examination of the code suggests that this message is being produced by drivers/block/ide-cd.c:ide_cdrom_probe_capabilities
printk ("%s: ATAPI %dX %s", drive->name, CDROM_CONFIG_FLAGS (drive)->max_speed, (CDROM_CONFIG_FLAGS (drive)->dvd) ? "DVD-ROM" : "CD-ROM");
Is this a bug or a feature?
Is it already known?
Is there a fix?
Actually, I don't need a fix since the drive is destined for a MSWin98 system. But I thought that this might be worth reporting.
Thanks,
