the bin86 RPM appears to be missing on the RH-6.1 installation, on CD-ROM and on ftp mirrors. As a side effect, the standard 'make yImage' kernel compilation fails with 'as86 missing'. As a first workaround I have installed the RedHat-6.0 RPM bin86-0.4-7.i386.rpm and I am now able to compile a kernel. Please make a RH-6.1 bin86 RPM available in 'updates'.
The bin86 package has been superceded by the dev86 package. Please use it instead.
