| |
I configured 2.1.82 with
CONFIG_SCSI=y # CONFIG_BLK_DEV_SD is not set CONFIG_CHR_DEV_ST=m CONFIG_BLK_DEV_SR=m # CONFIG_BLK_DEV_SR_VENDOR is not set CONFIG_CHR_DEV_SG=m # CONFIG_SCSI_MULTI_LUN is not set # CONFIG_SCSI_CONSTANTS is not set CONFIG_SCSI_LOGGING=y CONFIG_SCSI_AHA1542=y
and no other low-level drivers. At boot time the aha1542 driver says:
Configuring Adaptec (SCSI-ID 7) at IO:234, IRQ 10, DMA priority 7 scsi0 : Adaptec 1542 scsi : 1 host. Vendor: NEC Model: CD-ROM DRIVE:463 Rev: 1.05 Type: CD-ROM ANSI SCSI revision: 02 Vendor: NEC Model: CD-ROM DRIVE:463 Rev: 1.05 Type: CD-ROM ANSI SCSI revision: 02 Vendor: NEC Model: CD-ROM DRIVE:463 Rev: 1.05 Type: CD-ROM ANSI SCSI revision: 02 Vendor: NEC Model: CD-ROM DRIVE:463 Rev: 1.05 Type: CD-ROM ANSI SCSI revision: 02 Vendor: ARCHIVE Model: Python 25501-XXX Rev: 2.96 Type: Sequential-Access ANSI SCSI revision: 02 scsi : detected total.
I did:
# modprobe cdrom; modprobe scsi_mod; modprobe sr_mod
to load the needed modules. However, I get this error message:
# mount -t iso9660 /dev/sr0 /cdrom mount: the kernel does not recognize /dev/sr0 as a block device (maybe `insmod driver'?)
The system works well with 2.1.72. Ideally, I would like to have the AHA-1542 driver as a module too, but I get the message "Device or resource busy" when trying to load it. I'm using a Tekram DC-300B host adaptor.
