Partioning a drive with ez-bios

I have a 10Gb hd, but my system bios won't recognize over 8.4 Gb, so I
have a program called ez-bios controlling the drive so that I can use
all 10 gigs. But when I run the Linux fdisk, it doesn't recognize the
partion, and tells me there are no available sectors to create linux
partions, also it reports that my hd has 1027 cylinders, too many above
1024, please help, as I don't want to have to buy a motherboard that
will support >8.4 Gb hdds.
I have also flashed my bios with no luck.

Sounds like you're using the 2.0.x kernel; 2.2.x has better IDE geometry
detection (it detects my 9.1GB Seagate ST39140A correctly). So one fix is
to upgrade your kernel.

The other fix is to specify the correct geometry (cylinders, heads,
sectors). You can do this by entering "expert mode" in fdisk and changing
the geometry there. Once it's in the partition table, the kernel will
accept it as being true. Just be careful to get it right (check your HD
manual).

Either way, the partition your kernel is on (either / or /boot) has to be
within the first 1024 cylinders so the BIOS routines can read it. A tiny
(10-20MB) /boot partition will do fine.

Ditch EZ-bios, you don't need it for Linux and it's getting in the way. If
all your DOS drives (if any) are in the first 1024 cylinders and your
/boot is in the first 1024 cylinders, you should be fine.

Greetings,

Can anyone tell me what I might need to do to get my new
Panasonic LF-D101 DVD-RAM drive (its a rewriteable phase-change
optical drive) working with Linux? It works fine under Windows,
but Linux doesn't seem to recognize it.

Any help is appreciated.

1. Patritioning WD 8.4 GB drive and Linux and EZ-Drive/EZ-Bios

Hi

I just installed a Western Digital 8.4 GB drive on my Micron machine
with a Micronics M54Hi motherboard as the second drive.  This has the
PhoenixBIOS 4.04 which cannot support disks larger than 7.8 GB.  There
is a BIOS (v5.05) upgrade available from Micro Firmware but for $79!  I
installed the WD EZ-Drive software and it partitioned the drive in 4
with about 2.1 GB per partition.  I can see these partitions OK in Win95
(though I do have a spurious E: drive that cannot be accessed).

In Linux (RedHat 4.1 - yes, part of the reason of getting the new drive
was to upgrade to RH5.2), fdisk sees only the first partition of the hard
drive (as /dev/hdb1 with about 2.1GB) with the rest of the drive seen as one
partition with unknown type.  If I use linux fdisk to partition the disk
in what I _think_ is the same partitions as EZ-Drive used then Win95 sees
the first partition but cannot read the other three.  Repartitioning the
drive with EZ-Drive causes the original problem (i.e. can only see the two
partitions in Linux).  

I know Western Digital claims that EZ-Drive does not support Unix but
the Large Disk mini-HOWTO claims that Linux will work with EZ-Drive.  I
seem to be almost there.  Has anyone got this working or have any
suggestions?

Thanks in advance for any advice.
