Mitsumi FX-400B EIDE & Linux?

Post by Reed Mangi » Mon, 04 Sep 1995 04:00:00



Sorry for the newbie question!  I have been watching this group for
awhile and see that many of the posts are about recognizing cdrom drives...

I cannot seem to get Slackware to recognize my Mitsumi drive.  During
boot it always tries to detect at 0x300, irq 10.  My mitsumi is an EIDE
at 0x170, irq 15.  

I copied all the necessary files from my cd-rom to my hd (under dos) and
installed Linux from the hd.  Using lilo I pass this parameter:
mcd=0x170,15.

The boot process says that it recognizes the drive but later it says that
it cannot mount the cdrom because it is "not a valid block device".

Can anyone please help me out here?  Like I said, I am new to linux, but
I really want to work this out! :)

Thanks for your time and consideration,
Reed

You seem to have tried Mitsumi CD (non ATAPI/EIDE).  I have that drive
myself and it works fine, but as an EIDE CD-ROM drive, not a mitsumi
drive.  Slackware should find it and depending upon which EIDE controller
you have it installed, it will appear as something like /dev/hdc.

I don't think I am using the right kernel.  I am using 1.1.59.  I DID try
idekern and was able to mount the cdrom, but intermitantly...

What kernel version are u using?

Thanks, Reed

Had the same problem. downloaded a new ker from sunsite.
idenets and the cd appers.
check the dmesg after it boot and look for the /dev/hdb
 i also had to unlink the cdrom from /dev/nec260
and create a new link to it
ln -f /cdev/cdrom (remove the lin --- man ln)
ln -s /dev/hdb /cdrom ( something like that )
then mount /dev/cdrom just like a hard disk.

good luck

Sergio

While I greatly appreciate your help, I wish you would RMFP (Read My
F**king Post).  Actually I had to recompile my kerneral with ATAPI IDE
CD-ROM support!

***BEFORE*** I posted my question, I read the cdrom howto with my
slackware distribution *AND* got the newest version of that doc from
sunsite just to make sure I had updated info.

Sorry for the spew, I just really can't stand it when people use that
"RFTM" crap.  You had absolutely no idea what I did before I posted!

TYFYT! (Thank you for your time!)

1. Installing FreeSCO with EIDE Mitsumi FX-810s 8x CD-ROM

Has anyone had success with this?  Or, how about some comments and
hopefully advice?

My system is a Pentium/120 and all EIDE, with the hard disk on #1
(master) and the CD-ROM on #2 (master).  I prefer to have this
configuration for good performance, having read reports of seriously
degraded performance when the CD-ROM and HD are on the same port.

Need I say that both Windows 95 and Red Hat Linux install and run just
great, with no installation problems whatsoever?

I have tried "defbootstr ahslink=wd disable=dptr"; no dice.  The CD-ROM
is accessed (even when I don't use the defbootstr and just hit Enter at
the : prompt) but I either get an error (System Error 2:, followed by a
suggestion to reboot or power down) or the system hangs after displaying

Checking system state and loading installation files.

Please wait...

Yup, I waited a VERY LONG TIME! :-)

The CD-ROM spins up, and the access light flashes several times, but
nothing useful happens after that.

(After 9 installation attempts, it is now after midnight, and I'm
feeling rather burnt;
at this point I don't know whether SCO should be given an award for
releasing OpenServer for free, or scolded for releasing a UNIX product
with poor installation docs and insufficient support!  I may not be a
total UNIX wizard, but I am hardly a newbie, either.  I have installed a
number of UNIX-variants, ranging from Xenix 286 to Red Had Linux and
this one has been the most difficult of them all.  So much for the value
of experience and, for that matter, technological development, I guess
:-).  Now, I realize that some models of Mitsumi CD-ROMs have been a
little odd, but hey, if Microsoft AND the Linux developers can do it,
why not SCO???  Thank you for reading through this stressed-out,
late-night tirade -- not my usual style! :-)

Did I mention that I would greatly appreciate any help that anyone could
provide?

Thanks,

Jay Ts
