oh, I forgot to include the detailed info. kernel 2.4.1 when I do modprobe fdomain without the drive hooked up, I got scsi0: <fdomain> BIOS version 0.0 at 0x0 using scsi id 6 scsi0: <fdomain> TMC-18C30 chip at 0x140 irq 15 If I have the drive hooked up, I got scsi0: <fdomain> BIOS version 0.0 at 0x0 using scsi id 6 scsi0: <fdomain> TMC-18C30 chip at 0x140 irq 15 scsi0 : Future Domain 16-bit SCSI Driver Version 5.50 scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 2, lun 0 0x12 00 00 00 ff 00 scsi: <fdomain> abort Future Domain 16-bit SCSI Driver Version 5.50 scsi0: <fdomain> BIOS version 0.0 at 0x0 using scsi id 6 scsi0: <fdomain> TMC-18C30 chip at 0x140 irq 15 other (8), target = 2 cmnd = 0x12 pieces = 0 size = 256 sent_command = 0, have_data_in = 0, timeout = 0 in_interrupt_flag = 0 IMR = 0xfffa (masked), IRR = 0x4618, ISR = 0x0000 SCSI Status = 0x0b TMC Status = 0xc0 (interrupt) Interrupt Status = 0x98 (enabled) FIFO Status = 0x08 Int. Condition = 0x00 Configuration 1 = 0x8c Configuration 2 = 0x07 scsi : aborting command due to timeout : pid 0, scsi0, channel 0, id 2, lun 0 0x 12 00 00 00 ff 00 then keep on going until it cycle through all SCSI id. another question is, why would the card on SCSI id 6? there is no jumper on the board. so it's not really something I can change. thanks chen -- ~ __ Freedom of Choice 'v' / / __ __ __ __ __ __ __ // \ / /__ / / / \/ / / /_/ / \ \/ / /( )\ /_____/ /_/ /_/__/ /_____/ /_/_\ ^`~'^ --------------------------------------------------------------------------- Send administrative requests to [EMAIL PROTECTED]
