Hi, I have a TOSHIBA 24X atapi cd-rom drive. The current customized kernel takes a long time (20 seconds) trying to probe for this device during boot time. Al the other steps during boot up are quite fast. I was wondering if there are any specific lines that I could change in my config file to make this probing faster. I am running 2.2.5-STABLE and here are somem more details: 1) dmesg gives the foll wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <Maxtor 84320D5> wd0: 4119MB (8436960 sectors), 8928 cyls, 15 heads, 63 S/T, 512 B/S wdc0: unit 1 (atapi): <TOSHIBA CD-ROM XM-6102B/1106>, removable, accel, ovlap, d ma, iordy wcd0: 4133/4134Kb/sec, 256Kb cache, audio play, 255 volume levels, ejectable tra y wcd0: 120mm data disc loaded, unlocked 2) the relevant lines in my config file are options "CMD640" # work around CMD640 chip deficiency controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr disk wd0 at wdc0 drive 0 disk wd1 at wdc0 drive 1 #controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr #disk wd2 at wdc1 drive 0 #disk wd3 at wdc1 drive 1 options ATAPI #Enable ATAPI support for IDE bus options ATAPI_STATIC #Don't do it as an LKM device wcd0 #IDE CD-ROM Thanks, Narana.
