Last month when I started experimenting with openbios, I found the documentation to be misleading about which files to call from grub. Here's a patch to the README which I hope clarifies the matter:

trouble with cygwin
by Mark Wenning Jan. 24, 2005

cygwin ( http://cygwin.com ) is a linux shell /emulator that runs under Windows. It uses standard gcc and ld , We thought this would be the easiest way to get our developers going with OpenBIOS as a development simulator... Is anyone out there running OpenBIOS as an application under Windows (XP or 2000)?

Hi guys, I'm trying to build OpenBIOS under Cygwin . I get the following errors when I build it: wenning@SHARPSTICK:~/src/openbios/openbios$ make + Entering libc + Entering kernel + Entering toke + Entering forth + Entering modules + Entering drivers + Entering fs + Entering grubfs + Entering arch/x86 BUILDING plain.image ld: PE operations on non PE file. make[1]: *** [plain.image] Error 1 make: *** [sub-arch/x86-all] Error 2 any ideas?

bug in toke?
by Mark Wenning Jan. 11, 2005

Hi - We're looking at using toke, detok in our development process. Our current setup to tokenize device drivers uses a "script" similar to this: ----- start kng_sr_script ----- \ define these words for the tokenizer tokenizer[ 0 constant ?SYSTEM-ROM 0 constant COMMENT-OUT 0 constant ?DEBUG-TX 0 constant ?DEBUG-RX h# 0110 constant ibm-Code-Revision-Level h# 17D5 constant ibm-VendorId h# 5831 constant ibm-king-DeviceId h# 020000 constant ClsCode ]tokenizer fload kng_main.of ----- end kng_sr_script ----- Then in kng_main.of, we do: ----- start kng_main.of ----- .... tokenizer[ hex ibm-Code-Revision-Level decimal ]tokenizer SET-REV-LEVEL tokenizer[ hex ibm-VendorId ibm-king-DeviceId ClsCode decimal ]tokenizer PCI-HEADER FCODE-VERSION2 ... ----- start of code...----- The version of toke I downloaded doesn't like this for 2 reasons: 1. Constant declarations in TOKENIZER[ ... ]TOKENIZER blocks emit bytes/tokens to the output, so we get extra stuff before the PCI header. I don't think it should do this; code inside tokenizer blocks should not be in the output FCODE. Is this correct? 2. Previous constant declarations aren't being looked up/interpreted when in Tokenizer mode. For example, tokenizer[ hex ibm-Code-Revision-Level decimal ]tokenizer SET-REV-LEVEL causes a "empty stack: error. I have to change it to tokenizer[ 0110 ]tokenizer SET-REV-LEVEL to make it work. Is this a bug? I'm a little new to this; basically what I'm asking is if this behaviour is what was intended, or should we attempt to fix it and submit a fix to you.
