From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461) Description of problem: I just got my hands on a old Compaq Prosignia 300 and I'm trying to install RedHat 7.3. The computer is built on the EISA platform and reports only 16MB to the ISA command, as originally specified. It has 16MB onboard and the installer gets to the point where it says I don't have enough memory. I tried installing another 32MB and 24MB and entered linux mem=32M and linux mem24M The installer crashes when it tryes to create a RAM disk. The following is the error message: ext2-fs: unable to read superblock isofs_read_super: bread failed, dev=09:00, iso_blknum=16, block=32 Kernel panic: VFS Unable to mount root fs on 09:00 Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: See above. Additional info: I've tryed Mandrake 8.2 and experienced no problems.
Ok, I fixed it. Because RedHat 7.3 runs kernel 2.4.x I had to use a diffrent syntax than the one on the F3 help page. Instead of: mem=24M I wrote: mem=exactmap mem=640K@0 mem=23M@1M This worked. The bootdisk and affected documentation should be changed.
Jeremy do you see any problem having docs change this?
These specific Compaqs are weird... most hardware can have memory specified with mem=48M or whatever normally without problems. If you use the exactmap syntax, you have to specify holes as well, which cause more problems on most more modern hardware.
