Need help getting Acer CD-525E CD-Rom drive to work

Post by Brett Davids » Thu, 07 Sep 1995 04:00:00

Subject says most of it really. :-)

I have an Intel 486 DX/33 on a Total Peripherals motherboard.
I also have an Acer CD-525E Atapi compatible Cd-ROM drive from Taiwan.

I have used the IDECD 1.44Mb bootdisk along with the TTY144 rootdisk.
(I only have a Hercules mono screen at present).

The boot process says that /dev/hdc is the CD-Rom drive and finds it.
A bit later on I get an error message saying that
"BIOS32 extension were not found but are needed. Sorry."
When running the setup program, I press 7 for IDE/Atapi drive install
and then /dev/hdc. The setup program then runs around in circles forever.

Can you help me?

Following are the boot sequence messages.

**************** Cut here ****************
Loading ramdisk...
ide0: primary interface on irq 14
Floppy drive(s): fd0 is 1.44M, fd1 is 1.2M
FDC 0 is a 8272A
EATA (Extended Attachment) driver version: 2.31a
developed in co-operation with DPT

No BIOS32 extensions present. This release still depends on it. Sorry.
Partition check:
  hda: hda1 hda2
************** Cut here ***************8

hda1 is Linux main partition with 110Mb on it.
hda2 is a 14Mb swap partition.
The machine is a Total Peripherals 486DX, 33Mhz with 5Mb of RAM.

What are the BIOS32 extensions that it can't find? What are they
used for?

The CD-Rom drive supports atapi pio mode 2 for 8.33Mb/sec data transfer rate.
It's IDE Interface conforms to SFF8020 Atapi.
(Both of the above lines are according to the manual There are no other
configuration details in the manual, regarding IRQ's or the like).

I used the IDECD bootdisk which seems fine except for that BIOS32 message.
I have tried mounting /dev/hdc at the boot parameters option and have
generally had a great deal of fun (NOT) trying to get the thing to work.
Had no joy.

Are there any parameters I can put in at the boot options line to overcome
the problem?

Any suggestions? I'll try even the wacky ones!

1. Driver for Acer CD-525E CD-ROM

Hi there,

I have just purchased an Acer CD-525E CD-ROM drive that connects to an
EIDE controller card.  I used to use a Mitsumi drive with a CD-ROM
controller, but now I can't access the CD-ROM.  Does anyone know where I
can get a driver for this new CD-ROM or if there is a way of using Linux
without a driver?  I am using 1.59 kernel.
