Re: [9fans] Video mode problem after installation on QEMU
I found workaround. After installation need rebuild terminal kernel 'pcf', and replace installed, after that all seems works fine. Maybe need modify CD installation image? Thanks.

If differences can be identified, they should probably be eliminated. But it's hard to look. The real difference is the inclusion of a RAMdisk in pcflop, if memory serves. ++L

My approach would be to try to build 9pcf from sources as at the same date as 9pcflop.gz, probably build both and see how closely they match what gets installed. After that, it's binary division to find where things went wrong, I suppose. I'd offer to do it, but I know I'd never keep my promise :-( ++L

[9fans] Video mode problem after installation on QEMU
Hi all. During installation I chose 1024x768x24 vesa mode, and all was OK. But after reboot and logged under glenda, I have blank screen, also the same result after aux/vga -m vesa -l 1024x768x24 Any suggestion?

Not a useful suggestion, just a note to anyone who who has a little time and knows anything about the boot and installation processes that this needs fixing. This is the 4th or 5th time a first-time installer has had this trouble in the last week or two.

Use -vga std at the qemu command line. All of the modes work okay then. -- vs
