try the insmod again with IRQ and IO specified. insmod aha1542 irq=10 if that fails, insmod aha1542 irq=10 IO=<your value> What's the output of cdrecord -scanbus (pref. after the insmod) Original Message dated 05/06/2001, 16:35:42 Author: Jason Joines <joines@dexter.okstate.edu> Re: [SLE] ISA SCSI CDRW: I am using SuSE 7.1 with the 2.4.2 kernel from the SuSE ftp site and have a Phillips SCSI CDRW on an ISA Adaptec 1542 card. I have played around with isapnp until I now get this in my boot log. "Initializing PnP devices Board 1 has Identity b6 ff ff ff ff 35 68 63 0e: CSC6835 Serial No -1 [checksum b6] Board 2 has Identity 86 94 9c 73 43 42 15 90 04: ADP1542 Serial No 2493281091 [checksum 86] CSC6835/-1[0]{WSS/SB }: Ports 0x534 0x388 0x220; IRQ5 DMA1 DMA0 --- Enabled OK CSC6835/-1[1]{Game }: Port 0x3A0; --- Enabled OK CSC6835/-1[2]{Ctrl }: Port 0xF00; --- Enabled OK CSC6835/-1[3]{MPU }: Port 0x330; --- Enabled OK ADP1542/2493281091[0]{SCSI Host Adapter }: IRQ10 DMA5 --- Enabled OK done" This looks to me like everything would be ok, yet attempts to mount the device give "mount: /dev/sda1: unknown device". Also, in /proc/scsi/scsi is only one line that reads, "Attached devices: none". I tried to do "insmod aha1542" and get "Using /lib/modules/2.4.2-4GB/kernel/drivers/scsi/aha1542.o /lib/modules/2.4.2-4GB/kernel/drivers/scsi/aha1542.o: unresolved symbol isapnp_find_dev" I also found this in my boot log, "<6>SCSI subsystem driver Revision: 1.00 <4>3w-xxxx: tw_findcards(): No cards found. <3>request_module[scsi_hostadapter]: Root fs not mounted <3>request_module[scsi_hostadapter]: Root fs not mounted <3>request_module[scsi_hostadapter]: Root fs not mounted" Any ideas?
