When installing RH 6.0 built May 26 1999 on my new Sony Vaio PCG-505TR laptop, the Sony PCMCIA IDE CD-ROM drive boots the RH6 CD OK and (with the PCMCIA supplementary floppy) successfully insmods pcmcia_core, i82365 and ds modules, but cannot access the CD-ROM for installation with the following error messages in the system log window: <30> cardmgr[13]: Card Services release does not match! <30> cardmgr[13]: socket 0: Ninja ATA executing 'insmod ide_cs.o' <4> hdc: UJDB110, ATAPI CDROM drive <4> ide2: ports already in use, skipping probe <4> ide1 at 0x180-0x187,0x386 on irq 3 <4> hdc: ATAPI 14x CD-ROM drive, 128kb Cache <6> Uniform CDROM driver revision: 2.54 <6> ide_cs: hdc: Vcc=5.0, Vpp=0.0 <30> cardmgr[13]: executing './ide start hdc' <30> + cat: not found <30> + ./ide: /sbin/ide_info: not found <30> + usage: ./ide [action] [devicename] <30> start cmd exited with status 1 A workaround documented on the Linux Laptop pages for RH5.2 still works, to start linux with the following parameters: 'ide2=0x180,0x386 cdrom=hde' It is then necessary to change the /dev/cdrom symlink from /dev/hde to /dev/hdc after installation, since the PCMCIA drivers work as normal after RH6 is sucessfully installed. The bug seems to be in the PCMCIA installation floppy only.
