Further driver parameters:

irq1,irq2, etc. Only for ICP EISA Controllers with disabled BIOS (irq1, irq2,

etc. correspond with the IRQs of the ICP Controllers)

disable:Y deactivates the ICP driver

disable:N activates the ICP driver

reserve_mode:0 reserves no SCSI devices [*1]

reserve_mode:1 reserves all not-initialized removable hard disk [*1]

reserve_mode:2 reserves all not-initialized SCSI devices [*1]

reserve_list:h,b,t,l,h,b,t,l, reserves SCSI devices at the corresponding coordinates with

h=Hostadapter, b=SCSI Bus, t=Target ID, l=LUN

reverse_scan:Y reversed scanning order of the PCI controllers

reverse_scan:N normal scanning order of PCI Controllers according to the

system BIOS

max_ids:x x = number of target IDs per SCSI channel

(accelerates the boot process)

rescan:Y rescan all SCSI channels / IDs

rescan:N scan only those SCSI devices found during

system power up [*1]

[*1] The driver parameters reserve_mode and rescan:N require ICP Controllers with firm-

ware version FW 1.23.00/2.23.00 or higher.

The current default settings of the driver are:

"gdth=disable:N,reserve_mode:1,reverse_scan:N,max_ids:127,rescan:N"

If gdth is loaded as a module, these parameters can also be added with a special syntax.

IRQ parameters are entered as 'IRQ=' (e.g. IRQ=10). Several parameters are not separated

with a comma (',') but a space (' '). All ':' are substituted with '=', all 'Y' with '1' and all 'N'

with '0'.

Default: "modprobe gdth disable=0 reserve_mode=1 reverse_scan=0

max_ids=127 rescan=0"

G.7 Notes

Further interesting information:

/proc-Support:

Read of /proc/scsi/gdth/0, /proc/scsi/gdth/1, .. :

Displays the ICP Controller/SCSI busses, firmware version, driver version (e.g.: cat

/proc/scsi/gdth/0)

Write to /proc/scsi/gdth/0, .. :

gdth flush Flush all Host Drives of the ICP Controller

gdth flush drive Flush the Host Drive with the number drive

gdth wbp_off Disable Write-Back permanently

gdth wbp_on Enable Write-Back permanently

gdth wb_off Disable Write-Back for this session

(from Firmware version 1.15/2.15)

gdth wb_on Enable Write-Back for this session

(from Firmware version 1.15/2.15)

LINUX IS GREAT !
