Syslinux - Jan 2005 - Trouble with Syslinux 3.07 and USB-key

Hi,

I've a usb-key that boot regularly on a PC using syslinux 2.09; well, 
this PC (a thin-client) at the moment is the only PC that can boot from 
USB in my office... and it usually booted oretty well, without any hacks...

After changed to syslinux 3.07, it stopped booting, showing a simple 
"BOOT ERROR" message, nothing more...

Reverting to syslinux 2.09, it restarted to work...

Formatting the key, syslinux-ing it with 3.07 and recopying the 
software, it restarted working, but boot time is about 10 time 
slower.... minutes to load kernel and initrd instead of seconds...

Note: I'm using win32/syslinux.exe

Bye!

Formatting the key, syslinux-ing it with 3.07 (with clean key, this 
time) and recopying the software, it restarted to work, but boot time is 
about 10 time slower than 2.09.... minutes to load kernel and initrd 
instead of seconds...

I just released SYSLINUX 3.08-pre1.  I believe this should fix the 
performance regression for SYSLINUX/FAT in the 3.0x releases; it seems 
that due to a bug in the logic that computes contiguous I/O transfer 
blocks, the -s option was in effect always enabled.

USB turns out to be a red herring; it affects all boot media.

Please try it out and see if it helps your boot performance.

Hi,

Just tested.... but the boot continue to be really slow :o(

Say me which info I can send you to help you debug the problem... the 
BIOS is an AMI

It could probably help if in the "3.08preXXX" serie you wirte on the 
screen some debug output, like blocks size

bye!

Paolo

It works!  The speed is now like version 2.13.

Thanks!

Hi

pre2 lacks the win32/syslinux.exe file... :o(

If you can you directly send it to me, or upload an updated pre2, I will
test it immediately...

bye!
