Description of problem:
need to use ide=nodma for my RICOH CD-R/RW MP7083A
Steps to Reproduce:
1. load cdrom in to install rh 7.1
Actual Results: tries to boot of CDrom when I tried to install RH 7.1, but
Expected Results: install from cdrom perfectly
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.
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.
