Hi there.
Can I report what appears to be a problem with the latest IOmega
driver?
I was using the driver supplied with kernel 2.0.33 quite happily,
although it limited the transfer to the Parallel ZipDrive to
around 25k a second.
I 'upgraded' to the latest drivers, PPA 1.40, and found that I was
getting all sorts of errors when mounting ZipDisks, with no
consistency between the messages from one mount to the next, even
for the same disk. I even managed to corrupt a friend's ZipDisk
when trying to mount it ReadOnly !!!
I have carried out some basic investigations regarding this, and
found that the problems occurred when my BIOS had the parallel
port set to EPP mode - the problems went away when I changed the
setting to ECP mode, and with that setting, I get a transfer rate
of around 110k a second.
The above-mentioned friend is quite happily using the same drivers
(indeed, the same kernel - we transferred his kernel image to my
machine and rebooted under it with no change in the situation),
and gets no problems in EPP mode, which makes me suspect there's
more than one EPP chipset, and mine is one the current driver
doesn't handle correctly.
I'm no expert on debugging hardware problems, but am willing to
act as a test site for this chipset if somebody's willing to
provide directions on what to do. As a starter, here's some
details of my configuration:
1. /proc/cpuinfo
processor : 0
cpu : 586
model : Pentium 75+
vendor_id : GenuineIntel
stepping : 12
fdiv_bug : no
hlt_bug : no
f00f_bug : yes
fpu : yes
fpu_exception : yes
cpuid : yes
wp : yes
flags : fpu vme de pse tsc msr mce cx8
bogomips : 66.56
The actual processor is an Intel Pentium P166. In addition,
many of the chips on the motherboard have VIA stamped on
them so if that's a standard chipset, that's the one I have.
2. /proc/pci
