Description sjarrettsprague 2001-07-12 19:06:53 UTC

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2) Gecko/20010628

Description of problem:
need to use ide=nodma for my RICOH CD-R/RW MP7083A

How reproducible:
Always

Steps to Reproduce:
1. load cdrom in to install rh 7.1
2. dies
3.
	

Actual Results:  tries to boot of CDrom when I tried to install RH 7.1, but
dies.

Expected Results:  install from cdrom perfectly

Additional info:

I have had to put a line in my own init script to say

#disable DMA for CD-ROM
/sbin/hdparm -d0 /dev/hdc

otherwise I wouldn't have been able to use cdrom post install

"RICOH CD-R/RW MP7083A" is the string from
cat /proc/ide/hdX/model ? if so I'll add it to the "dont do dma" list

thanks for the report.

Comment 2 sjarrettsprague 2001-07-13 07:29:52 UTC

Yes. RICOH CD-R/RW MP7083A is in /proc/ide/hdc/model. Look forward to RH7.2 
being easier to install!

Thanks for the info, added to the no-dma list for the next build.
