           Summary: parallel port access is slow due to high cpu usage
                    (eprom burner)
           Product: Wine
           Version: 0.9
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-binary
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: pkk(a)spth.de


Whe I burn EPROMs with the willem eprom burner (software at
http://www.willem.org/ZIP/epr097ja.zip) wine needs a lot of cpu power. Parallel
port access speed scales with CPU speed.

I run wine as root and have added the following registry keys:

[HKEY_USERS\S-1-5-4\Software\Wine\VDM]

[HKEY_USERS\S-1-5-4\Software\Wine\VDM\Ports]
"read"="0x278-0x27f,0x378-0x37f"
"write"="0x278-0x27f,0x378-0x37f"

[HKEY_USERS\S-1-5-4\Software\Wine\VDM\ppdev]
"378"="/dev/parport0"
