CheepoBios 1.12 beta for K7S5A
Based on ECS 021129 beta

chb1129.rom 	lan / non-lan Version
chb1129f.rom 	lan / non-lan Version with fastwrites enabled 

Release notes:


- Adjust timing for stability and compatibility ;)
- Onboard lan Auto Detection newly introduced by ECS doesn't seem to work properly and may prevent non-lan boards from working. I have fixed that by disabling onboard lan by default. Just enable it if needed ;)
- Fixed Athlon XP1700+ was detected as 1800+
- ECS support sent the 021129 beta bios to a user as a solution to the "lost cmos" problem. My board doesn't have this problem so you try and tell me!!!! 

- FSB modes reprogrammed:

	"100/100 MHz" changed from 99.6 to 100.9 MHz
	"133/133 MHz" changed from 132.77 to 133.9 MHz
	"100/133 MHz" changed from 99.6/132.77 to 100.9/133.9
	No more underclocking by default! 

- Several FSB modes added. New list of available modes:

	100/100 MHz
	100/133 MHz
	133/133 MHz -> Default modes

	H/W Trap (hardware default)
	112/112 MHz
	124/124 MHz
	138/138 MHz (reprogrammed from 137.3 to 138.0)
	150/150 MHz
	166/166 MHz -> Already present in the "OC" bios

	110/110 MHz 
	133/100 MHz (Now 133.9/100.9) 
	143/143 MHz
	147/147 MHz
	110/147 MHz
	133/166 MHz
	200/200 MHz
	
	Please note that the "166 MHz no-boot issue" hasn't been dealt with
	in this bios modification. It seems that bios timings need to be adjusted to allow
 	booting at such speed. This issue could also affect the 200/200 settings.

- Extra memory settings:
	- RAS Precharge Time=2T
	- RAS Active Time=4T, 5T

- Full screen logo can be enabled/disabled via bios menu

- A few hidden bios options have been enabled with amibcp. Please notice that none of these settings have been fixed or reprogrammed at all.
	
	- PCI Latency Timer
 	- PCI slot #1 to #4 IRQ priority
	- IO APIC
Note: there is no need to enable PCI IDE Busmaster anymore, it was already present as an available option in the ecs bios

The default values for these settings, as well as all other settings except onboard lan, remain the same as in the original bios.

 

I wish to thank Jinxter, tw.p, Bench400 and Beheerder: deblokker mij, fellow bios modders
at www.ocworkbench.com/ecs for their useful ideas, discussion and testing
